Is your feature request related to a problem? Please describe.

No response

What you want

Windows NT 3.1 does not support ATAPI CD-ROM drives, but it does support SCSI host cards and it might support SCSI CD-ROM drives. Mentioned during initial Windows NT install is the Adaptec AHA-152x, which as it turns out is documented and has a well known Linux kernel driver that may be of use for study: https://www.kernel.org/doc/html/v6.8-rc4/scsi/aha152x.html and https://elixir.bootlin.com/linux/latest/source/drivers/scsi/aha152x.c

Then, IMGMOUNT could attach that drive to SCSI emulation (in the same way that you can attach the drive to IDE emulation).

Describe alternatives you've considered

No response

Additional information

INT 13h may have to support talking to the SCSI emulation instead of IDE, at least in a way Windows NT would support if the user wants to attach the hard disk image to SCSI emulation instead of IDE.
