SCSI question
Hello again,
With my extra memory problem solved, I've been working on getting through
the rest of my setup problems (on an IBM Thinkpad 560Z).
I have a SCSI pcmcia card (Adaptec, APA-1460 SCSI Host Adapter). When
I did my build (2.0.38 from floppies), I included SCSI support. But,
I didn't have any devices connected to the SCSI card, it was just in a
slot. I have since connected a jaz disk and a Toshiba CDROM to the card.
Now when I boot, the system can ID the devices and gets the right SCSI
addresses. When I boot, I have a cd in the cdrom but no jaz disk
loaded.
Here's the pertinent part of the dmesg output:

.............................................
One thing I notice is that the Adaptec SCSI driver it's loading seems
to be for a different model (aha152X not apa1460).
I took a look at the SCSI-programming howto, but this doesn't seem to
be what I need, and it's pretty darned intimidating. I thought
perhaps the problem wast that /dev/sr0 and /dev/sda don't exist, so I
tried to figure out how to use MAKEDEV, but there doesn't seem to be
much documentation for it. Any suggestions?
Finally, is there a driver out there for the IBM portable CDROM
drives (card services identifies it as "IBM", "PCMCIA Portable CD-ROM
Drive")? This plugs into a pcmcia card which is labeled "IDE", but NT
thinks it is a SCSI device.
Sorry for the long mail, and
Thanks in advance,
Biff
