OS can't find simulated SCSI CD-ROM

[ren stimpy]

 

Hi folks,

I want to emulate NextStep OS 3.3, the i386 variant.

In order to install it on the hard drive, it expects to find

a CD-ROM drive on a SCSI bus, rather than IDE/ATAPI.

The OS comes with many drivers for a variety of SCSI cards.

So far, I'm finding that only the AMD driver even finds

the hardware that I'm asking Qemu to support.

But the CDROM is detected as having 0 bytes.

Can anyone assist with getting this to work?
I can provide a list of drivers the OS comes with.

Thanks.

 

Here's how I'm currently trying to run Qemu.
