[HECnet] Bringing up a MicroVAX 3100-80

[William Pechter]

When I did the VAX station all I did was burn the iso image normally.  The SCSI drive was a Toshiba 4x tray drive with a switch for 512 byte sector support. 

Any switch settings on the DEC drive? 
You also should be able to use dd on linux/unix to write the install iso to another scsi disk to see if it boots. 

Also--what is the scsi rom error message. 
Is it using the weird DEC scsi cable like the DECstations?

I hooked up the RRD42, burnt the OVMS-7.3 ISO image on a CD-R, and tried 
to boot dka400, didn't work. The internet is flush with discussions 
about "special format" CD-ROM, ODS vs ISO, 2048 byte vs 512 byte blocks, 
etc.

My MacBook refuses to brun the VMS 5.5-2H4 ISO from VAXHAVEN ("invalid 
disk image"). So basically I have to research and find a way to burn a 
CD-ROM in the necessary format that will boot the MicroVAX into DCL so 
that I can repair the CONTIGUOUS issue on DKA100.

I am sure lots of people here have done this - any tips welcome while I 
am trolling the internet.
