[HECnet] Bringing up a MicroVAX 3100-80

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?

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.
