[Info-vax] P400 on DS10/DS15

[Rod Regier]

It's possible to use ORCA on "headless" system thru the serial console.

F8 becomes <ESC>8, etc.

This was the magic I used with the SA6402 on the DS15 FWIW:
(Tip of the hat to Stephen Hoffman)

Expand DS15 HEAP to permit SA6402 co-processor to boot up and communicate with DS15 primary processor:

>>>set heap_expand 2mb
>>>init

The SA6402 menuing and initialization is designed for video console operation and PC keyboard mappings. Switch DS15 to video console mode if not already in that mode.

There is no boot support for the SA6402 on a DS15 operated in SERIAL console mode!

>>>set console graphic

To perform initial or subsequent video console configurations of the SA6402 attached disks (ORCA interface):

>>>run bios pya0

n.b. failure to provide the SA6402 with an expanded DS15 heap will result in the SA6402 failing to boot into its BIOS and omission of the logical disks delivered by the SA6402.

Logical disks created under the SA6402 are named DYAx offline, but tend to be named DKCx online.

To configure first logical volume as default boot device:

>>>set bootbios pya
>>>INIT
>>>set bootdef_dev DYA0

If you have the set bootdef_dev command complaining about DYA0 being an invalid device, try booting from DYA0 and then performing the SET command. Suspect there is a "state" issue with the SA6402 that interacts with DYA0 virtual device characteristics.

If you are still stuck try:

>>>set bootdef_dev dya0.0.0.2004.2

If you did the boot, try:

>>>SHO BOOT*

and copy the value associated with booted_dev
