I think there may be a bug in cpmtools.

For a disk images where DSM = 255 (total disk blocks = 256
e.g. YAZE 512K) cpmtools appears to be reading directory block
numbers as 16-bit values rather than 8-bits. This results in
an 'Attempting to access block beyond end of disk' error.

I'm using this version of cpmtools:

http://www.cpm8680.com/cpmtools/

though a 2008 binary I had displayed the same problem

Can you retest under linux as the Windows build is much older than the newest code on the author's site?

Don't have linux but anyone who does may grab one of the 512K disk images
included in the YAZE distribution:

http://www.mathematik.uni-ulm.de/users/ag/yaze-ag/devel/

If my surmise is correct, this definition which defines a disk capacity of
exactly 256 blocks will fail when extracting files with 'cpmcp':

diskdef yaze512
seclen 128
tracks 512
sectrk 8
blocksize 2048
maxdir 1024
skew 1
boottrk 0
os 3
offset 128
end

Reducing the number of tracks by one (blocks=255) and cpmtools now works:

diskdef yaze511
seclen 128
tracks 511
sectrk 8
blocksize 2048
maxdir 1024
skew 1
boottrk 0
os 3
offset 128
end

dxforth,
I'm not finding any 512 Kbyte images. I just downloaded all three *.ydsk images and I only have
larry@debian:~/Downloads/yaze$ ls -alt *.ydsk
-rw-r--r-- 1 larry larry 262272 May 9 07:10 testdsk.ydsk
-rw-r--r-- 1 larry larry 1048704 May 9 06:07 z80asm.ydsk
-rw-r--r-- 1 larry larry 1048704 May 9 06:03 wordstar400.ydsk

Can you point me to a 512 Kbyte image? I'd like to work on the same image you are using.

I see you have also added the OFFSET 128 and SECTRK 8 stanzas.

I'm using the z80asm.ydsk image of 1048704 bytes.

My cpmtools definition is
diskdef yaze1m
# BSH 4 BLM 15 EXM 0 DSM 511 DRM 1023 AL0 0FFH AL1 0FFH OFS 0
seclen 128
tracks 8192
sectrk 8
blocksize 2048
maxdir 1024
skew 1
offset 128
boottrk 0
os 3
end

and my libdsk definition is
[yaze1m]
description = yaze1m image
cylinders = 8192
heads = 1
secsize = 128
sectors = 8
secbase = 1
datarate = DD

I used hexedit to locate the directory of z80asm.ydsk, and broke out the USER {0..15} area(s).


hexedit z80asm.ydsk

Directory is at 0x0080 = 128 Decimal

This looks sane to me, but I haven't tried extracting the files yet to make sure they are sane.

I forgot to post my versions of libdsk and cpmtools I'm using on Debian 9.x - 64 bit.

cpmtools ver 2.21
libdsk 1.5.14

I get the error message that you refer to with sector = 512 with the Wild Turkey flavour of cpmtools (cpmcp). If I use CpmtoolsGUI I get the error message "Assertion failed: blockno<d->size, filecpmfs.c,line 278
If I change diskdefs to sector = 511 I get no error with either version of cpmtools.

This appears to confirm your bug report.

I tried it on my rpi linux and strangely not getting cpmls to work with either definition in dskdefs. I am sure cpmls is picking up the right diskdefs. Something for another day.

The images appear to be in the Windows version of yaze-ag under bin/disks but do not come in the tar file for the unix/linux flavour.
try turbo-modula-2.ydsk

All the *.ydsk files seem to work fine except for the CPM3_SYS.ydsk. I can not get a directory listing for
that file. cpmtools built with libdsk does not like the format for some reason.

Here are the directories for the other files.

Hello Victor,

...

You want to know how you can use the CP/M-programm Z80ASM inside the
yaze-ag Emulator.

Bevore I discuss this I want to say you that you have to transfere
your assembler-source to a CP/M-disk which is used by the emulator.
You can use the cdm utility to transfere between a CP/M-Disk and unix.
Cdm (CP/M disk manager) is part of yaze-ag.
See "man cdm" to look to the commands and use the help command
about the "cp" command inside cdm ("help cp") to see how you can copy
and convert Unix files to CP/M files.

The Z80ASM:

Z80ASM is a comercial product by SLR.
I load the Z80ASM from www.retroarchive.org[/cpm/lang/lang.htm] there is
many commercial software for CP/M-80. There you find also Z80ASM in the file
SLRASM.ZIP. Inside the archive there is also the CONFIG.COM for the Z80ASM.COM.
There is also the archive SLR_MAN.ZIP with the dokumentation for Z80ASM.

I have a documentation for the SLR180+ (a further development of Z80ASM) but
the most options are idendically with the Z80ASM.

The assembler uses the source file format which is used also by
M80 (Microsoft).

Syntax of Z80ASM:

Z80ASM [filename][/options][,[filename][/options][,[filename][/op]]]]

Command line options are used to modify the default operating
characteristics of Z80ASM.

SLASH OPTION SUMMARY:

A : absolute mode. Output file is COM.

C : default output to the console

D : don't do LOWER to UPPER case conversion.

E : execute LOWER to UPPER case conversion.

F : selects full listing (2 passes through source)

H : generate HEX file as output

K : kill all console I/O and detach

L : list output partial (1 pass through source).

M : generate microsoft rel file as output

N : new OPTION byte.

P : enables output to the list device.

R : generate standard rel (SLR format) file as output.

S : generate alphabetized symbol table.

T : input time and date string

U : declares undefined symbols as external.

X : generates cross-reference.

Y : disable cross-reference

6 : selects M-Rel output, 6 significant.

7 : selects M-Rel output, 7 significant.


Some options (long form):

A The A option selects absolute mode operation and a
default output file type of COM.

F The F option selects FULL listing mode. This option
forces Z80 ASM into 2-pass mode, generating a
listing output on the second pass to the appropriate
device. Note that by default the disk driver is enabled.

H The H option selects absolute mode and binary output
type compatible with the Intel HEX format.
This output may be directed directly to the CON or
LST devices for output straight to an ICE or PROM
programmer.

L The L option selects one-pass listing mode. This
listing is similar to the F-mode fill listing
expect that forward references list as undefined
in the fenerated code columns. Note that by default
the output will go to the same disk drive as the
source file.

M The M option forcees relocatable mode. The binary
output file has the default extension REL, and the
format generated is compatible with the microsoft
releocatable format.

P The P option makes the PRINTER or CP/M list device
output driver the default output for listing-type
outputs. Any Listing, symbol table, or crossreference
output selected will be sent to the CP/M list device
by default.

R The R option is used to select relocatable operation.
The output file is REL, and the format generated is
SLR Format.

S The S option selects the generation of an alphabetized
symbol table. The output goes to the disk device by
default. The output contains symbol names, types, and
values. The number of symbols per line depends on the
selected page width and the number of significdant
characters selected.

T The T option is used to specify a time and date string
for use in generating listings. Any following characters
(up to 16) up to the next comma, semicolon or carriage
return are used as the time and date string. This option
must used as the last slash option.

U The U option (ignored in absolute mode) instructs Z80ASM
to automatically declare any UNDEFINED labels as externals
to beresolved by the linker. LOCAL labels CANNOT be external.

X The X option selects cross-reference generation. This
option forces two-pass mode (/F), and the output will
go on the end of the listing file, or optionally to a
seperate file (see config.com).

6 The 6 option performs an implied M option, and selects
6 significant character generation for globals and
externals. This overides the default selected by config.com.

7 The 7 option does the same as 6 expects that Z80 ASM will
generate 7 significant characters for globals and externals.

Z80ASM generate M-REL format (option 7) by default.

If you start Z80ASM without a file, it goes in an interactive mode. There
you can assemble also more than one assembler source. You stops the Z80ASM
with CTRL-C (or Strg-C).

So I hope this is enought and you can use Z80ASM.

If you use the microsoft rel format you can use the L80 (microsoft) or
the LINK.COM (Digital Research) to link to a COM-file.
See the Y.SUB on drive P: (BIOS-Souce files) for an example where I compile
all BIOS-files with Z80ASM and link all (with the linker of Digital Research
(LINK.COM)) to BNKBIOS3.SPR.
You find the syntax of LINK.COM with "HELP LINK" if the emulator runs.
I mean you find the syntax of L80 also on www.retroarchive.org.

If you have more questions write an email to me.
If you find an Error in yaze-ag, let me know about it.

Good luck :-)

I've only tried cpmcp and cpmls. The latter won't report an error since
it only lists the directory AFAIK.

blocks = 256 is the highest number of disk blocks CP/M can handle and still
use 8-bit numbers in the directory entries i.e. 0-255. I suspect cpmtools
is getting confused on this 'corner case'. Since it would rare for a real
disk format to result in blocks=256 (DSM 255) it's likely the problem went
unnoticed.

The YAZE distribution I used:

yaze-ag-2.50.0-rc3-x86_32bit-generic.exe

It included these 512K images:

bios3.ydsk
turbo-modula-2.ydsk
unixlike.ydsk

OFFSET=128 is to bypass the ydsk image header - at least I hope that's
what OFFSET is for. Unfortunately cpmtools makes little effort to document
entries in a diskdef or explain how it uses them.

There was no particular reason for my choice of 'seclen' 'tracks' 'sectrk' -
only that they should combine to produce a disk capacity of 256, 512, 1M,
2M and 4M blocks respectively. AFAIK only when BOOTTRK <> 0 would
'seclen' and 'sectrk' be critical.

dxforth,
Here is an excerpt from my newdefs.doc fie that explains the definitions and how they are calculated.

New 22DISK definitions require the following information:
DENSITY xx,xx
CYLINDERS x
SIDES xx
SECTORS x,xxxx
SKEW x
SIDE1 0 x,x1,x2,x3, , ,xn
SIDE2 x x,x1,x2,x3, , ,xn
ORDER x
BSH x
BLM x
EXM x
DSM x
DRM x
AL0 x
AL1 x
OFS x (or SOFS x)
COMPLEMENT (unlikely)

New LIBDSK definitions require the following information:

[title]
description = DESC The description of the format as shown by (for example) dskform–help.
sidedness =TREATMENT How a double-sided disk is handled. This can either be alt
(sides alternate – used by most PC-hosted operating systems),
outback (use side 0 tracks 0-79, then side 1 tracks 79-0 – used
by 144FEAT CP/M disks), or outout (use side 0 tracks 0-79, then
side 1 tracks 0-79 – used by some Acorn formats). If the disk is
single-sided, this parameter can be omitted.
cylinders = COUNT Sets the number of cylinders (usually 40 or 80).
heads = COUNT Sets the number of heads (usually 1 or 2 for single- or double- sided).
sectors = COUNT Sets the number of sectors per track.
secbase = NUMBER Sets the first sector number on a track. Usually 1; some Acorn formats use 0.
secsize = COUNT Sets the size of a sector in bytes. This should be a power of 2.
datarate = VALUE Sets the rate at which the disk should be accessed. This is: HD, DD, SD or ED.
rwgap = VALUE Sets the read/write gap.
fmtgap = VALUE Sets the format gap.
fm = Y or N Sets the recording mode - Y for FM, N for MFM.
multitrack = Y or N Sets multitrack mode.
skipdeleted = Y or N Sets whether to skip deleted data.

The LIBDSK Data rate will be one of:
RATE_HD, /* Rate for High-density disc - 1.2Mb in 5.25" 96 tpi drive, or 1.44Mb in 3.5" 96 tpi drive */
RATE_DD, /* Rate for Double-density disc - 360k in 5.25" 48 tpi drive, or 720K in 3.5" 48 tpi drive */
RATE_SD, /* Rate for Double-density disc - 180k in 5.25" 48 tpi drive, or 360k in 3.5" 48 tpi drive */
RATE_ED /* Data rate for 2.8Mb 3.5" in 3.5" 96 tpi drive */

New CPMTOOLS definitions require the following information:

diskdef title
seclen xxx #= Sectors xx,1024
tracks xx #= (Cylinders * Sides) = 80*2 = 160
sectrk xx #= Sectors 5,xxx
blocksize xxxx #= (128*(BLM+1)) = 2048

skew x #= may be 1 thru 6, or so
/* OFS is the number of tracks to the start of the Directory. In the case of 22DISK's SOFS, it's the number of SECTORS to
the start of the Directory. For cpmtools the OFFSET stanza can be used for the actual number by Decimal Bytes to the
start of the directory. But, the boottrk stanza must be ZERO for the offset to be valid.
example:

This cpmtools, 8/16 and DSM 255 thing sounds very familiar. I
think this has been discussed sometime in the last few years,
but I can't seem to find the posts right now.

Thanks for that.

Would I be correct in assuming CPMTOOLS can't correctly handle disk images
such as Kaypro II ? IIRC Kaypro II miscalculated their DPB values,
allocating more blocks (AL0,1) to the directory than the DRM+1 required.
CPMTOOLS has only MAXDIR to tell it where the data blocks begin.

I confirm that on the Win version of cpmtools.

What fails on my cpmtools is:

D:\cpmtools>cpmcp -f yaze512 bios3.ydsk 0:*.* dest

It will however correctly extract files with a size of 1 block (2048 bytes) or
less.

So cpmls is reading the directory information correctly and calculating file
sizes correctly. The problem appears to be in (at least) cpmcp.

Interesting. If it can be confirmed the latest official release is
still failing on file copy, the info can be forwarded to Michael (or
whoever is the current maintainer).

Cannot comment on the rest, but since I added the 'offset' keyword I can
confirm that's precisely the application it's intended for: skipping system
tracks that aren't a multiple of sector size and/or previous volumes in a
hard-disk image.

Michael has updated the sources to correct the problem but advises
it is untested. Here is the link:

http://www.moria.de/~michael/cpmtools/files/cpmtools-2.23-snapshot.tar.gz

Being a Win user, I'll leave it to the more experienced C & Linux
users to compile and verify. Should there still be issues, Michael
has requested a disk image and few files.

I was not aware of the secret hidden folder, and was waiting for Michael to release 2.22. I've now got a bunch of patches sent off to Michael and hopefully we can get 2.22 or 2.23 released soon. Looks like there needs to be more testing, so I guess that's on any of us with the necessary expertise.

I should also note that Michael states that 2.23-snapshot is very un-tested. I also know of a bug in 2.22 that causes segfaults, and is still in 2.23-snapshot. So, caveat emptor. 2.21 is the current, official, stable release.

Comparing cpmtools-2.22.tar.gz with cpmtools-2.23-snapshot.tar.gz...

OK:
"cpmfs.c" is fixed and looks ok.

NOT OK:
"fsck.cpm.c" and "fsed.cpm.c" were overseen!

Every ...size>=256 needs to be changed to ...size>256.

Very easy to find...

$ fgrep -n ">=256" *.c
fsck.cpm.c:244: if (sb->size>=256) block+=(dir->pointers[++i]&0xff)<<8;
fsck.cpm.c:277: if (dir->pointers[i] || (sb->size>=256 && dir->pointers[i+1])) ++used;
fsck.cpm.c:491: if (sb->size>=256) block+=(dir->pointers[++i]&0xff)<<8;
fsck.cpm.c:497: if (sb->size>=256) block2+=(dir2->pointers[++j]&0xff)<<8;
fsck.cpm.c:546: if (sb->size>=256) block+=(dir->pointers[++i]&0xff)<<8;
fsed.cpm.c:120: if (sb->size>=256) sector|=(((mapbuf[entry*32+16+ ++i]&0xff)<<8));
fsed.cpm.c:360: if (drive.size>=256)

I forwarded this to Michael and he has updated the 2.23 snapshot to include these as well. That is the best way to get cpmtools updated: e-mail to Michael.

That looks like the same problem I just sent a fix for to Michael. Try using the latest 2.23 snapshot, which should not require any changes and also includes the fix for the segfault. http://www.moria.de/~michael/cpmtools/files/

That diskdef does not seem to match the disk image. The directory entries in the image are for a DPB that has the total number of blocks being <= 256 (one byte block numbers), but the diskdef computes out to 2048 blocks total (two byte block numbers). This results in cpmtools thinking the first block of CPM.SYS is 0x1110 which would correctly be beyond the end of the disk. I'd have to see more of the disk image to tell what the diskdef needs to be.

I found the image "z80asm.ydsk" and took a look at it, and that one does show two byte block numbers:

000e0: 01 5a 38 30 41 53 4d 20 20 43 4f 4d 00 00 00 80 .Z80ASM COM....

00110: 1c 00 1d 00 1e 00 1f 00 20 00 00 00 00 00 00 00 ........ .......

So it would appear that the image you are looking at is a different format. The header of these ".ydsk" images seems to contain a DPB in it, perhaps we just need to see the first 128 bytes of the .ydsk file you have.

so, the DPBs differ. Here's a program I threw together to read the DPB from the .ydsk header and create a cpmtools diskdef from it. Provided I did not screw up, that should work on your image too. http://sebhc.durgadas.com/getydskdef.c

It works for me on z80asm.ydsk (using my enhanced cpmtools to embed the diskdef on the commandline, e.g. cpmls -d -f "$(getydskdef z80asm.ydsk)" z80asm.ydsk).

I should have clarified, the 'getydskdef' tool does not require my enhanced cpmtools, it just prints to stdout the diskdef, which you can just paste into a diskdefs file and add a name for.

$ getydskdef z80asm.ydsk
diskdef
seclen 128
tracks 64
sectrk 128
blocksize 2048
maxdir 1024
skew 1
offset 128
boottrk 0
os 2.2
end

Yes, Now I have a correct Definition for BIOS3.YAZE:
yaze512
seclen 128
tracks 32
sectrk 128
blocksize 2048
maxdir 1024
skew 1
offset 128
boottrk 0
os 2.2
end

All of the files I have checked so far are SANE.

I patched the old Windows sources with the '256' fix and it works for me.
BTW my diskdef is:

diskdef yaze512
# BSH 4 BLM 15 EXM 1 DSM 255 DRM 1023 AL0 0FFH AL1 0FFH OFS 0
seclen 128
tracks 512
sectrk 8
blocksize 2048
maxdir 1024
skew 1
boottrk 0
os 3
offset 128
end

Yours diskdef results in an image size of 128*8*4096 = 4MB.
4MB/2048 blocksize = 2048 blocks ... which is greater than 256.
It's no wonder cpmtools is reading it wrong.

Yes, i finally see what it should be for yaze512. Senior moment after senior moment.

diskdef yaze512
# BSH 4 BLM 15 EXM 1 DSM 255 DRM 1023 AL0 0FFH AL1 0FFH OFS 0
seclen 128
tracks 512
sectrk 8
blocksize 2048
maxdir 1024
skew 1
offset 128
boottrk 0
os 3
end

[yaze512]
description = yaze512 image
cylinders = 512
heads = 1
secsize = 128
sectors = 8
secbase = 1
datarate = DD
