I don't remember what I said. In any case, it has SCSI support, but no
built-in support for a particular SCSI card (you need a module).

That would be a stretch.

Once I include slhc. But you also need a new pppd than
what BL provides.

Not sure.

I think it needs gcc-2.95.3. I don't have SW91 source, but the 2.4.19
documentation says gcc-2.95.3 is the minimum.

Yes, it is very annoying.

True, but printers and mice ought to work.

Both.

No. I don't know how to make a bootable memory stick (yet).

Depends on the hard drive. USB1.1 is ~10mbps which is faster
than parallel port but slower than my slowest hard drive.

Probably. Or grub if it would work on a memory stick.

Yes, but the image might be large without compression.
Not sure if it would need to be resized for a different sized
memory stick. I have 128MB.
