Title: OS3.9 install on A3000 problems
Post by: kenwood on February 21, 2007, 10:43:20 PM

Hi everyone.

After a long hiatus from the Amiga world (enforced somewhat by a leaky battery and an A3000 motherboard), I am back, and discovering things I though I had (and also have) forgotten.

So, long story short, the A3000 is now the proud owner of a brand new motherboard, and all is working fine. I installed 3.1 again last night and all is well.

So, I got myself an OS3.9 CD from SoftHut (awesome Amiga dealer - very helpful), and here is where the problems begin.

I have an external SCSI CD-ROM (actually a burner), but I don't have the cable to go from the A3000's on board SCSI controller (being the DB25 to large centronics cable). I did have one, but who knows where it has gone.

I did have an A4091 SCSI controller lying around (as you do), and installed this fine. I have the latest buster (rev 11) in this machine too.

If I run any utility that scans the hardware, the CD-ROM can be found on 2nd.scsi.device (the A4091), but I can't mount a cd onto the workbench.

Assuming I needed a driver to do this, I looked on the net, and came across a driver in dms format on the 'Amiga Hardware Database' site. All looks good but I cannot for the life of me expand this dms file.

I have a vague recollection that it is a diskmasher file, and it expands out onto a floppy disk, being an image of the original.

So, can anyone point me to a way to expand the DMS. I tried Directory Opus but no good. I have no issues with having to buy some software from a developer etc if necessary.

Sorry for the long 'story' but I am trying to give everyone a picture of what I am seeing.

BTW, there is a working cybervision card in this machine too.

Thanks one and all. I hope someone can point me in the right direction.

Regards.

3.1 comes with a rudimentary CDFilesystem. Get Icon Information on CD0 in the Storage/DOSDrivers directory and adjust the device and unit tooltypes accordingly. It should be  enough to get a 3.9 emergency disk made. After booting from that I believe you'll be using CacheCDFS, which will allow you to finish the install.

EDIT: Oh, and remember to mount CD0 (doubleclick) after you've adjusted it. Drag it to Devs/DOSDrivers to make it permanent.

You can find the DMS program in Aminet. Look for DMS.lha.

You will also need lha.run from Aminet in order to extract .lha formated files.

Thankyou for your replies. I will try this tonight and see how I go.

Take care.
