[rescue] Sparcstation 10 woes during boot

[Ethan Hawke]

Hi Zoltan,

Yes that's correct, although it will depend on what PROM version you are 
running, as the exact messages will differ.

Here's an example from my SS20 (My SS10 has a far older PROM with 
different boot messages)

[...]
Allocating SRMMU Level 1 Table
Level 1 Table allocated, Available Memory 0x1ffafc00
Mapping RAM @ 0xffef0000
RAM mapped, Available Memory 0x1ffafa00
Mapping ROM @ 0xffd00000
ROM mapped, Available Memory 0x1ffaf800
Mapping ROM @ 0x00000000
ROM mapped, Available Memory 0x1ffaf000
ttya initialized
Cpu #0 TI,TMS390Z55
Cpu #1 Nothing there
Cpu #2 TI,TMS390Z55
Cpu #3 Nothing there
[...]

And yes, it's the keyboard that depends on what output to use, although 
the POST messages will always be printed via ttya.

Is all your memory seated correctly? Especially the first slot?

Hopefully this helps,
Ethan
