We can't read from floppy on Pentium II, SCO Unix rel. 5.0.0b and 5.0.2
Pavel Jordak
Help!
We are preparing a new server for our customer based on Pentium II (M/B
DTK with chipset FX) and have succeeded in installing the customer's SCO
Unix 5.0.0b. We had problems with a keyboard. We tried several keyboards
but none of them worked more than for several commands and the only
thing we could do was to power off the machine.
So we decided to reinstall the system to the release 5.0.2.
Unfortunately errors reading the diskette occured every time after
displaying the hardware configuration and installation aborted. When we
rebooted the rel. 5.0.0b and tried a command "dd" for copying from the
diskette to /dev/null we got three versions of outputs:
1) xxx records in
xxx records out that's OK
2) the same and after a second:
Warning: floppy: Read error on dev 2/64, block=0 cmd=0x03 status=0x01
3) the warning at first and then:
dd: read error: I/O error (error 5)
0+0 rec. in
0+0 rec. out
Both floppy and diskette are OK, we tried several ones.
Where's the problem? We are crying with Beatles: HELP!
Jiri.

Two problems. For the keyboard hangs on OSR5.0.0, you could use SLS
oss424a. However, this problem was corrected in OSR5.0.2 and the SLS is
not needed.
For the floppy problems, there are a couple of kernel variables that you
can change. These will help *only* if the floppy controller has a FIFO.
Unlike serial ports, I don't believe the floppy controller manufacturers
have all gotten around to adding the FIFO. But many controllers do have
it.
It's a little tricky to use the patch during installation. You need to
start with a working SCO Unix system. Make a *copy* of the N00 (boot)
floppy that you will be using. Then do this (using the copy):
# mount /dev/fd0 /mnt
# uncompress < /mnt/unix > /tmp/unix.N00
# echo fd_enable_FIFO/W 1 | _fst -w /tmp/unix.N00 -
# echo fd_FIFOthresh/W f | _fst -w /tmp/unix.N00 -
# compress -H < /tmp/unix.N00 > /mnt/unix
# umount /dev/fd0
You should now be able to boot and install using this modified N00 disk.
You will also need to modify the same variables in the link kit, after
installing; you'll have trouble accessing the floppy until you do (but
that won't prevent you from booting from the hard disk). Once
installed, edit /etc/conf/pack.d/fd/space.c. Change the value of
fd_enable_FIFO to 1 and fd_FIFOthresh to 15. Relink, reboot, and things
should be fine -- *if* you have a floppy controller with FIFO.

Hi,
find at SCO SSL library for :
'I'm getting floppy read errors with known good media and hardware on OSR5'
Perhaps ...

There is a supplement OSS424 (keyboard BTLD). You may get it from:
ftp://ftp.sco.com/SLS/oss424*
or
ftp://ftp.vse.cz/pub/vendor/SCO/ftp.sco.com/SLS/oss424*
On SCO OpenServer 5.0.0b you need install also lot of another supplenets.
The base supplements are:
SCO OpenServer Release Supplement 5.0.0d ftp://ftp.sco.com/Supplements/rs500d
SCO Networking Supplement Release 1.0.0 ftp://ftp.sco.com/Supplements/net100

The problem reading a floppy disk is described in IT script
http://www5.sco.com/cgi-bin/ssl_reference?483535
but here isn't a solution for the installation proces. Maybe you can
boot from 5.0.0b installation diskette with keybord BLTD and then install
5.0.2 .
