RomWBW cpm3

[Derek Cooper]

Hello,

Does anyone have instructions for installing cpm3 ? I have tried to find the cpm3.sys file and cpm loader file. With no luck. I have tried to extract them from the HD image or FD image file but cpmtools will not read the image file? I've tried with the -f wbw_fd144 and others but non work.

I need to write the system tracks from the booted system, I don't have a CF card adapter in my computer.

Has anyone done this ?

Derek

Hi Derek,

Sure, I suggest the following:

You need 3 files from the distribution package.  Look in the Binary/CPM3 folder.  You want CPMLDR.SYS, CPM3BNK.SYS, and CCP.COM.  Boot to ROM Z-System on your RomWBW system and transfer those 3 files to your RAM Disk (via XModem, etc.).   You will need to know which drive letter has been assigned to your CP/M 3 slice -- ASSIGN command may help here. Assuming the desired CP/M 3 slice is assigned to drive F, do the following:

• Use SYSCOPY to place CPMLDR.SYS on the boot track of your CP/M 3 slice.   The command would look like "B:SYSCOPY F:=A:CPMLDR.SYS".
• Copy CPM3BNK.SYS to the CP/M 3 slice, but call it CPM3.SYS.  Something like "B:COPY A:CPM3BNK.SYS F:CPM3.SYS" would do this.
• Copy CCP.COM to the CP/M 3 slice.  Something like "B:COPY A:CCP.COM F:" would do this.

That should to it and you should then be able to boot CP/M 3 by specifying the corresponding disk unit and slice from the loader prompt.
Below is a session log capturing this process in action.  Please let me know how you do.

Thanks,

Wayne

Thanks for that, it's more or less as I thought except for the CCP.COM.

Anyway I have looked for the files you said:=

"Look in the Binary/CPM3 folder.  You want CPMLDR.SYS, CPM3BNK.SYS, and CCP.COM"

I downloaded the last to distro releases,  RomWBW-v3.0.0-Package.zip and RomWBW-v3.0.1-Package.zip neither have the files in them, the CPM3 folder does not exist in the binary directory?

I can find things like cpmldr.asm in the build directory, do I need to assemble this file?

Thanks

Derek

Sorry Derek, my brain is stuck on the dev branch because of the upcoming stable release.  The location of the files I gave you is correct, but only in the development snapshot.  The stable releases are deficient in this regard.  That is why I changed things in the dev branch.

Anyway, yes, you are correct that you need to build the contents of the  Source/CPM3 directory in order to get these files.  Assuming Windows, open a command prompt in the Source\CPM3 directory and run "Build.cmd" from there.  This will just build the CPM3 binaries and the 3 files I specified will be created in the Source/CPM3 directory.

Sorry for my confusion.

Thanks,

Wayne

Yeah Success, cpm3 booted under ROMWBW 3.01

Thanks Wayne.

[Wayne Warthen]

Cool.

[Tom Plano]

Sorry to necro-post but I a question related to these instructions as well as the documentation in the repo for creating boot-able images. Is CPMLDR.COM compatible with DS/HD drives? These are known good drives and the directory storage works fine but I cant seem to get cpm3 to boot off them. The official docs note 3.5inch 1.44MB drive format images and harddrive images, but thats it. Im wondering if there is some limitation that I dont know about or if I have some other bug.

I get as far as

CPMLDR error:  failed to open CPM3.SYS

<<<

even though that file report fine when I boot cpm3 off the harddisk(created from romwbw images)

Hi Tom,

Should work fine, but I haven't tried booting it on a floppy in a long time.  Let me test and let you know how I do.

Thanks,

Wayne 

[Wayne Warthen]

Yeah, looks like something is amiss with the floppy boot of CP/M 3.  Sorry.

I will look at this tomorrow.

Thanks,

Wayne

[Wayne Warthen]

I have checked in a fix for CP/M 3 booting.  This issue only applied to the dev branch.  The issue is fixed starting with RomWBW Development Snapshot v3.4.0-dev.9 which may be procured as usual from the RomWBW GitHub Releases page.

Thanks and credit to Tom Plano for finding this problem.

Thanks,

Wayne

Happy to confirm that this fix works. As an aside, I really need a CF reader for my PC. Updating all copies of tools and apps is a real pain otherwise, and its easy to miss things.

Very happy to hear you confirmed this Tom.  Always good to get a second opinion on my testing!

Indeed, the manual update process is quite painful and error-prone.  A USB attached card reader for a PC/Mac/Linux box is about $15 on Amazon -- well worth it.

Thanks,

Wayne
