[ES40-developers] SCSI support for OpenVMS has arrived

[Camiel V. <iam...@gm...>]

Hi Again,

I haven't been able to get my hands on a KZPCA yet, (some of you had
suggestions who to ask, I'm pursuing those leads now) but in the
meantime, I took a good look at the KZPAA card I do have. It's a
53C810-based card, which is fairly similar to the 53C895. The good
news is that this card does not have any firmware. Due to the
similarities with the 53C895 it turned out to be not that hard to come
up with a working emulation. I just successfully booted OpenVMS off an
emulated SCSI disk.

I've committed the new code to the CVS repository. It will also be in
the next release. You'll need to change your config file, replace
53c895 with 53c810, and all scsi-disks should be in the 0.0 - 0.6
range (sorry, no wide scsi on this card).

Camiel.
