Creating a boot disk in OS3.9 with CD drivers

[Gojirax]

This might sound a little lame, but I'm QUITE out of practice with my Amigas.

- I have an A1200 with OS3.9 pre-installed and no CD-ROM.

- I have an OS3.9 CD.

- I have an Amiga 4000d with a blank hard drive and 3.1 ROMS and a CD-ROM.

- I have no boot floppy that will allow my A4000 to see the CD drive.

- How can I use my A1200 to create a 3.9 boot disk for the A4000 that will load the CD drivers?

I haven't checked my IDE-Fix floppy yet, but since I have no functioning operating system floppies I'm not sure how to get the A4000 up and running.

Specs:
My A4000 has 3.1 ROMS and a Warp Engine 040 accelerator. It was a Video Toaster system at one time, and I was able to boot it up with the old OS 3.0 120 meg IDE drive, but had no CD Rom support.

I'm just new to OS 3.9 and back when I setup an Amiga from scratch I had my OS 3.1 disk set and my IDE Fix disk and was able to get everything setup from there!

Thanks,
Jack

You have about 880K or so of space so you will need the following folders and files:

C (folder)
 Setpatch
 Loadwb
 Mount
 Copy
 Delete
 Dir
 Assign
 Binddrivers
L (folder)
 CacheCDFS
S (folder)
 startup-sequence
 user-startup
T (folder)
Devs (folder)
 mfm.device
 devs\Dosdrivers (folder)
  CD0
  CD0.info

The CD0 file is a text file which tells AmigaOS which device to use (default is scsi.device) and unit to use for
your CDROM device.
The startup-sequence is required to load Workbench.
Remember to use 'Install DF0:' to add a bootable boot block to your disk.

Or you could just create an OS3.9 Emergency Disk using the OS3.9 installer, then copy the CD0 mountlist from a Workbench 3.1 floppy. You will also need atapi.device from IDEfix as the CD-ROM on the A4000's IDE interface will be on atapi.device.

Awesome! That's exactly the information I needed!

Thanks so much!

I'll give that a go. (I don't have a working 3.1 boot floppy, but I can make the disk from the list above, and add atapi.device from my IDE Fix disk.)

Ok, I tried to make the boot floppy and it boots to AmigaDOS, but gives an error "Version failed with error code 20" and doesn't load workbench.

I've created the file and folder structure noted above and used the "Install DF0:" command to make it bootable.

What am I missing?

[Thomas]

The Version command is missing from the C folder.

You should check Startup-Sequence and copy all commands used to the C folder.

Also you don't need the T folder and mfm.device, but you need "AmigaOS ROM Update" in Devs, otherwise the CD drive will not be recognised by the IDE controller.

And you should delete user-startup, it only works with your HDD and will give error messages when used on the A4000.

Do you have the contents of the OS3.9 CD somewhere on your HDD ? Then simply copy the contents of the Emergency-Disk (not Emergency-Boot) folder to the floppy and create that CD0 icon afterwards.

Bye,
