As always, Gerhard, you are correct. Lots of lights on the VGX boards 
including the GE6. IO3B blinks a bit then stays off.

I didn't trust my serial cable too much so I built a brand new one, 
connected to the GM3 db9 and I got some output there, starting at:
NOTE: PROM checksum (0x513825)
all the way to
NOTE: end of PROM based diagnostics
GM PROM (Mon Jun 11 20:43:29 PDT 1990)

Yeah, I haven't set the time yet, cause I couldn't get to the console.

So, anyways, the diagnostic ran fine.

So I turned the Crimson off, connected the new serial cable to tty 1 and:

System Maintenance Menu

1) Start System
2) Install System Software
3) Run Diagnostics
4) Recover System
5) Enter Command Monitor


But bummer too... this Crimson was supposed to be 256MB VXGT and it 
turned out 128MB VGX... The other box is 0MB VGX...

Alright, let's try hinv:

Option? 5
Command Monitor.  Type "exit" to return to the menu.
> > hinv
               SCSI CDROM: Controller 1, ID 6
                CPU board: IP17 75 MHZ
   Instruction cache size: 16 Kbytes
          Data cache size: 16 Kbytes
 Secondary I/D cache size:  1 Mbyte
              Memory size: 128 Mbytes

The PROM hinv is not as verbose as the IRIX hinv, is it.

Alright then, let's try to boot this sucker. Too bad I dont know how to 
set the output to the monitor instead of the console. I'd like to make 
sure the keyboard is working... "set output video"? Well, let's try 
using the console for the install.

System Maintenance Menu

1) Start System
2) Install System Software
3) Run Diagnostics
4) Recover System
5) Enter Command Monitor

Option? 1

                             Starting the system...

               To perform system maintenance instead, press <Esc>
open(dksc(1,2,8)sash) failed, errno=5

Error: boot device not responding.
Unable to continue; press <enter> to return to the menu:

Hmmm.... Okay, maybe I need to go thru 2) to boot off the cdrom?

So I tried:

System Maintenance Menu

1) Start System
2) Install System Software
3) Run Diagnostics
4) Recover System
5) Enter Command Monitor

Option? 2

                         Installing System Software...

                       Press <Esc> to return to the menu.

Insert the installation CD-ROM, then press <enter>:
Unable to open "dksc(1,2,8)" error = 5
Unable to continue; press <enter> to return to menu:

Same thing... So It seems like it doesn't like my Toshiba XM-3501, which 
I tought were very SGI friendly... Does it have to be at a specific SCSI 
id? Specific bay? It's currently residing in the top half height drive 
bay. I tried both the 5.3 and 6.2 CDs, but I dont see activity on the 
CDROM (altough I hear some seeking).

Getting closer. In fact it's a good thing I had this small victory last 
night. Before I looked at the crimson again, I had decided I'd be 
playing with the Challenge L and altough the power supply AC good led is 
on, when I turn the key, nothing happens :O Argh. So now I have to track 
down yet another problem.

So I was about ready to load all 3 desksides in my car and dump them in 
the lake (not really, but man did it not look good at that point). And 
then I made the new cable and finally I did get something going on the 
Crimson. Altough, until I can use the keyboard and mouse and use it, it 
ain't over.
