I've tried debugging the driver. It gives an invalid opcode exception (which keeps retriggering because the BIOS or MS-DOS refuses to handle it fully). It tries to execute opcode 66h(The 80286+ operand size prefix byte opcode. I'm running a 80186 processor, so it doesn't exist on that processor).

Is there a IDE CD-ROM driver that runs on a 80(1)86 processor?

So you want a cdrom driver that supports a 8086
considering cdroms came out at roughly the same time as the 486 I dont think you'll find one

Maybe vogons should host a new section called "superfurry's this hardware/software doesnt work with my 8086 emulator"

Afaik CD-ROMs are SCSI devices. Would a 8086 SCSI driver detect the CD-ROM IDE drive? Are there any 8086 SCSI drivers? (Atm two SCSI commands are supported: Get capacity and Read sectors(essentially a modified ATA read sectors command with 2048 byte sectors instead of 512 byte sectors))

Edit: What SCSI commands are mandatory in a CD/DVD-ROM drive? Should all CD/DVD drivers be able to work with those implemented?

See if this helps

No. No real SCSI driver is going to understand ATAPI.
