I solved the problem: incorrect pins on empty slots of VME backplane.

Thanks Horun. I have my internal SCSI card in slot 7 - it is the only slot that provides internal SCSI connection. I also tried external SCSI card on slots 10 and 11. But it makes no difference. I have read the available documentation. The only thing that I cannot find for 100% is how the empty VME …

Thank you, guys. Here are the additional facts: The two SCSI adapters are: Sun P/N: 501-1149 "Sun-2" SCSI host adapter, internal (not SCSI 3, my bad) Sun P/N: 501-1217 "Sun-3" SCSI host adapter, external The first one is shown on the attached picture. The disks used are: Fujitsu M2624SA - this one …

I'm trying to revive an old Sun-3/260. I managed to boot it over network but I'm unable to connect a SCSI disk. I tried two different SCSI adapters, each being SCSI-3 and each with different cable. I also tried several SCSI disks that were tested as OK on a Sparc or a PC. I used internal SCSI cable …

Much appreciated!

The following variables booted NT Setup, which froze, however (second picture) ...

Still the same result @hyoenmadan. I think I need to find proper values of those variable. I keep experimenting. See the printenv output. It is default one since the battery is dead. I noted that ARC changes something but it is gone once I power off the machine. I set up sorrow1 account of IRC but …

thanks @hyoenmadan I was able to start * NT Setup - see the picture. When ESC is pressed the program terminates. When ENTER is pressed or countdown reaches zero, there is black screen again and error "VrOpen returned d"

No, I passed \ppc\setupldr as parameter to veneer.exe - the whole command reads: boot cdrom:,\PPC\VENEER.EXE \PPC\SETUPLDR I discovered that it uses some default path based on what scsi devices are attached: If only the cdrom is attached if boots from multi(0)scsi(0)cdrom(6)fdisk(0)partition(1)\ppc\ …

Well there is no such graphical setup of NT options. Only SETENV command (can also be set from menu). I'm not sure that it is the same. Tried but no luck so far ...

After having provided parameter \ppc\setupldr I succesfully booted Windows NT Setup. However, it says that CDROM partition 1 is corrupted ...

Thanks @hyoenmadan ! Partial progress. I managed to boot into ARC Interface Version 3.0. However, it tries to immediately load osloader.exe from cdrom directory \os\winnt\ (where there is none) and terminates with "Bad patch"error. Maybe, it needs some boot parameters set?

Thank you guys. I have read the articles and seen the video already before. But it did not help. It seems that I have different firmware version as @hyoenmadan pointed out. Mine says 1.2 RM11 and has much less features than the one in the video made by @SquallStrife. It lacks NT support and (for …

Hi, Recently I became a proud owned of PowerStack II. It works fine and boots Linux. I would like to try Windows NT but after research I learnt that I'm missing some Motorola disks. Namely: - PPC Boot Disk (Available from Motorola) - Arcinst.exe (Available from Motorola) - FW.IMG on disk (Available …
