[SunRescue] SS10, Openboot PROM 2.25, how to program it.

[L. Brignolo]

There is this Sparc10, 36mhz, 1.08gig, 32MB, ethernet, scsi port, aui,
parallel and serial, and a external CD, Solaris 7, but no c, no perl, etc..
Wanted to install Solaris8, and Solaris 8 needs 64MB, 1.7GB.

Then Purchased and installed a 2.25, hoping to put 2  32mb dimms later.
But at boot time is giving messages like:

"CPU#0 TI,TMS 390Z50.
CPU#1 nothing there
..2, 3..
Probing Memory Bank #0 16 MB RAM
Probing Memory Bank # 1 nothing there.
..2,3=16,4,5,6
Probing Memory Bank #7 at 2,00  cgsix

Rom Rev. 2.25 32mb serial 314891.
Boot device /iommu/Sbus/ledna at f,400010/le at f,c00000 File + args:
Lost carrier (Tranceiver cable problem?).
Timeout waiting for ARP/RARP Packet.
Cable problem or twisted pair hub link disable.
Use the PROM command help ethernet (and loops in these 4 last lines)."

Looks like PROM is reading an old configuration;

If that is true, how to program this replacement prom?

If that is not true, what is happening, what could I do now to boot up?

I am new to Unix, so any help will be highly appreciated.
