[Simh] EXTERNAL:Re: simh on MAC os (booting problem)

[Hittner, David T (IS)]

Also FYI, VAX VMS CD's are blocked at 512.

The RRD line is 'special' in that it can read 512 byte sectors, and are
required to be jumpered that way for VAXen if they have a blocksize
jumper.

I don't if that makes a difference in the 'dd' dump of the CD you show
below.

I've never used the 'bs=2k' modifier when dumping VAX CDs before.

I would suggest trying to boot directly from the CD device... I think
you can just point readcd to /dev/disk1 to creat an 'better' ISO
image... I know for making Solaris CD images I needed to use readcd vs
dd as readcd could deal with different sessions, and sector sizes...

Hi,

I followed the howto on the http://simh.darwinports.com/ for
installing the simh port on my MAC OS (10.6.4).

Then I dumped the content of the installation DVD to the file (trying
to install the OpenVMS system):
dd if=/dev/disk2s0 of=vaxvmscd.iso bs=2k

And created the system file:
dd if=/dev/zero of=vaxvmsssys.iso bs=512 count=9600000

Made the ini file:
LOAD -r KA655x.BIN
ATTACH nvr nvram.bin
ATTACH RQ0 vaxvmsssys.iso
SET RQ0 RA90
ATTACH RQ1 vaxvmscd.iso
SET RQ1 RRD40
SET CPU IDLE=VMS
BOOT CPU

Then when I try to boot from the cdrom I got this error:

sh-3.2# simh-vax -v vaxvms.ini

VAX simulator V3.8-1
do> LOAD -r KA655x.BIN

I don't know how to move forward. I would appreciate if someone could
help me.
