Either that or the other way around. From the looks of the quote above you only need the partition.
Memory is terrible, sorry :)
On my system (CentOS 5.6) I see the /dev/cdrom device which is symbolically linked to /dev/hda (which makes sense - it's the only IDE device I have in the machine). There is no hda1 or other devices for the partitions. fdisk /dev/hda comes back with an invalid partition table.
I remember how it went now - I was doing it on a Mac which uses a BSD disk structure. I dd'd the disk device (/dev/disk6) and it wouldn't work. I then dd'd the slice that reported as the actual volume (/dev/disk6s0) and it worked a charm.
I don't know how that's represented in Linux, however. Also fdisk won't show a partition table for a CD-ROM, I don't believe, because they are not structured as hard drive partitions. I put my VMS VAX CD-ROM in my Ubuntu box and the Disk Utility reports it at /dev/sr0 which is a SCSI ID but my Microserver has a weird disk controller.
I honestly don't know how to approach it unless you have something like gnuparted to hand to look at the disk?

Your unix flavor may be different.
Or use a cdwriter program that writes to disk, like Nero on Windows does.

Subject: Re: [HECnet] SIMH on CentOS 5.6
Thanks for the response. I think my issue has something to do with making the ISO image. I used 'dd if=/dev/cdrom of=cd.iso' which made a 676Mb file. But using this file gives me the error. I then tried attaching directly to the cdrom drive in vax.ini using 'attach -r rq3 /dev/cdrom' and it worked! I was able to do a full installation from the actual physical media.
Does anyone have any pointers for making an ISO image of the CD? Am I doing it wrong? I would like to make a backup of the disk because I'm already on my second physical copy and would like to back it up before I lose it again :)

Hello All,
I'm trying to compile and run SIMH on CentOS 5.6. I've followed the instructions at http://www.wherry.com/gadgets/retrocomputing/vax-simh.html but when I try to boot from the CD image, I get:

The KZPSA is a differential scsi controller. It supports dual hosts and may be used as a cluster interconnect (data only, no cluster control messages).

Here's a photo of mine, can you draw the bit I need to change onto it, or the general area:
http://sampsa.com/wp-content/kzstyleboard.jpg
That picture reminded me of something. I have what I thought was an extra long
and overly complex PCI SCSI card in my stash. It has the same Intel i960 as
the card in the picture but doesn't have the extra daughter board. It is
marked KZPSAPS and has a single 68 pin external SCSI connector and five
resistor packs commonly found as terminators on old-style (ie non-low-voltage)
differential SCSI cards.
I tried firing it up in my AS1000A and found that SRM sees it as follows:
SHOW CONF
12 DEC KZPSA pke0.7.0.12.0 SCSI Bus ID 7
SHOW DEV
pke0.7.0.12.0 PKE0 SCSI Bus ID 7 R01 A11
VMS (7.1-2) sees it as:
Device PKA0:, device type KZTSA/SCSI (SIMport), is online, error logging is
enabled.
Error count 0 Operations completed 24
Owner process "" Owner UIC [SYSTEM]
Owner process ID 00000000 Dev Prot S:RWPL,O:RWPL,G,W
Reference count 0 Default buffer size 0
Anyone know what (if anything) is special about this card?

Peter Coghlan.

So I'm willing to live with the single storage array I have for now, and am thinking of acquiring say off ebay, a second controller.
Which model should I go for? I only need one port but would like it to support as large a logical drive as possible (well, I've got 7x18 GB drives in a stack to use)..
Suggestions?
