My current setup
- A2000 with 2MB CHIP, 3.1 ROM, OS 3.9
- TF536 with 64MB and IDEtoSD as boot drive (scsi.device)
- A2091 SCSI controller with 2MB (2nd.scsi.device)
- Plextor 12X SCSI CD-ROM, termination enabled, configured as ID 5
Essentially, I'd like to use the A2091 for the CD-ROM drive. I don't really care about speed, I just need it to work from time-to-time. Initially after installing the A2091, SetPatch was dying with a Software Error/GURU. I found that disabling the 2MB onboard the A2091 (via jumper) fixed that issue. I read about all sorts of issues with the TF536 and Zorro II fast ram, so I wasn't surprised. I have enough fast on the TF536, so that is fine. CD-ROM transfers are very slow, but they work.
The weirdness:
I'm now at the point where my system will only boot (in a reasonable amount of time) if there is a CD-ROM in the drive on boot. Without a CD, the system sits for minutes and will eventually boot. However, after that, when I load a CD in the drive and attempt to mount the CD0, the device will load, but it will not show up as a volume. I'm assuming there is some ready signal from the CD-ROM that the A2091 requires.
I tried variations of the auto-boot enable/disable jumper on the A2091. If auto-boot is disabled the system boots quickly, but when I mount the CD0 device, the device loads, but it will not actually mount the volume.
In short, if I leave a CD in the drive, have auto-boot enabled on the A2091, I can mount CD0 and the volume/media is accessible. No CD in the drive on boot, no volume/media is accessible after inserting a CD and loading CD0. With auto-boot disabled on the A2091, I can't mount the volume after boot.
It seems like I need to be able to re-initialize/re-scan the A2091 after the system is up? Boot-up time is longer when there is a CD in the drive, so I'm really hoping to eliminate that requirement. Note: I always manually mount the CD0 device so I don't use up buffers and stare at the unused volume on the desktop for 99% of the time I don't need it.
Any ideas? I appreciate the help.
