Hi all,
I've got some ugly dirty VAXstation lately, an 3100/M76 and two
3100/M38 (if I remember correctly).
I've cleaned the M76 and got it to work. Inside is an 200MB RZ24 Disk
ans since I want to boot some Unix this is pretty small.
I have a bunch of IBM DCAS3330 4Gig disks that where a good fit I think,
but there is a problem with the System disk size on the VS3100..
The limit is coming from using six byte SCSI commands instead of the then
byte versions in the boot software. I googled a litte and found this:
:Yes. It's a limitation imposed by the boot ROMs.
Just ran into it
:(again!) a few weeks back and DEC reminded me yet again. Some confusion
:exists because -- I think -- some models of the 3100 were
:field-upgradable to have a new ROM set capable of supported >1 GB boot
disk.
No member of the *VAXstation* 3100 series support system disks larger
than 1.073 gigabytes, and there are no ROM upgrades available.
There are some members of the *MicroVAX* 3100 series that support or
can have console ROMs upgraded to support system disks larger than
1.073 gigabytes.
I do have KA43 V1.2 Bootroms in the M76, so the question is:
Are there newer ROM versions than 1.2 und is there support for larger
System disks? Burning Roms is no problem. Does someone have a newer
firmware version?
I know that I can use the 200MB Disk to boot and use the larger for data,
but at least I do have a mechanical problem here, I had to make some
plastic Bumpers to mount the additional disk in the VS3100 on the lathe.
I would better use the RZ24 in one of my PDP 11's...
Kind Regards,
Holm

I think that I have a spare 1GB SCSI disk, maybe two. Free for the
cost of postage. Shouldn't be too much from UK?DE, if I use surface
post.

I do not know whether V1.2 is the latest or not but I do know that
I've never heard of boot ROMs for any VAXstation 3100 that support
greater than 1.073GB boot disks for OpenVMS. (For Unix-like Oses then
I think you can partition the disk and all will be well ... it's only
the boot process that uses the console disk drivers).

OpenBSD is currently installing (flawlessly so far) but I think I'll know
in approx an half hour if I can boot the installed OS.
OpenBSD has sized the a partition with 900Mbytes so all the needed files
for booting should be below 1 GB.

I can netboot the openbsd kernel with included ramdisk, look at the

I can hdo a shutdown with halt and a boot dka400, this boots the
OpenBSD from the IBM Disk. But I can't cold boot from the disk
after power up...

If you mean that you have the console set to boot on power up and it
won't
do that, then that's probably because the console detected an error of
some
sort. Since it seems that the disk works (since you can boot it when the
console doesn't get in the way - and perhaps when you issue a B command
at the console?) then I guess that your errors on SCSI A are the issue.
I *think* that the wiring inside the M76 is such that there are two SCSI
buses: the internal one and the external one. If you do not have a
terminator
on the external bus then that may cause an error and that may cause the
power-on boot to fail.
This is just a guess though.

I suspect somthing like this. I had strange
problems like yours with
IBM disks too.
