I recently acquired an external Iomega Floptical drive with SCSI interface. I'd like to use this instead of a regular 3.5" floppy drive, so it has to be bootable and it should be assigned to drive letter A. Therefore I need a SCSI controller with a BIOS that supports Floptical drives. I have an Adaptec AHA-1542CF ISA SCSI controller, which supposedly should have BIOS support for Floptical drives according to the installation guide (http://download.adaptec.com/pdfs/installation … ha1540cf_ig.pdf). It says:
SCSI Device Configuration and Advanced Configuration Options: These screens are accessed from the Configuration screen described above. The AHA-1540CF/1542CF offers a number of options for advanced applications. Fast SCSI, Floptical support, and an alternate floppy controller address are enabled here.
However, that section within its BIOS configuration utility doesn't contain any option for enabling Floptical support. I do have an option for bootable CD-ROM support, which isn't mentioned in the installation guide. That got me thinking, could it be that they axed bootable Floptical support in favor of CD-ROM in later revisions of the BIOS?
I found this post mentioning that there were 3 different BIOS revisions for the AHA-1542CF: v2.01 (1993), v2.10 (1994) and v2.11 (1995). My card has v2.10. Perhaps v2.01 does have Floptical support?
Is there anyone with an AHA-1540CF or AHA-1542CF who has an other BIOS revision and would be willing to check the BIOS configuration utility for Floptical support? I'd also like to hear from people who have an AHA-1540C or AHA-1542C (so no Fast SCSI support) or the AHA-1542CP (which should be PnP). I suspect that the 1542CP won't have support, because it's newer, but the AHA-154xC will probably have it.
Thanks in advance!
