Leaving Octane out, I can identify these versions:
Code: Select all
part# eeprom id
V10, Fuel, old rev. 030_1725_00x ASTODYB
V10, Fuel, new rev. 030_1826_00x ASTODYV10
V12, Fuel 030_1726_00x ASTODY
V12, Tezro 030_1884_00x ODY128B1_2
'AST' is for 'Asterix', the codename for Fuel. 'ODY' is short for Odyssey, the codename for VPro graphics.
If you scan the 'hinv' forum, you will see that in all modded O350's with a V10 or V12, it identifies itself as ASTODY, ASTODYB or ASTODYV10. Looks like nobody butchered a Tezro to mod an O350
Now, I suspect that changing the contents of an EEPROM is possible from the L1 using some more or less undocumented calls (this is an entirely different discussion
), but changing the part number is a different game. Unless they changed everything for VPro on Fuel/Tezro, the part number is stored in a NIC chip, which is written once (at the factory) and cannot be modified. It would have to be replaced with a new one with the correct part#.
Inside the IRIX kernel, a device driver can scan for NIC part numbers using nic_vmc_add(): http://techpubs.sgi.com/library/tpl/cgi ... info_set.z
This would be the logical way to make the software tell the two cards apart. It is also how IRIX activates the keyboard & mouse ports on an (Onyx2) IO6G, but not on an Origin 2000 (IO6).
So, in order to "make a fortune", you would have to
1) Have a bunch of the correct late rev. V10's
2) Have a bunch of dead V12's to rip the NIC chips off.
3) Hope you can actually change the EEPROM
3) Replace the part# label stickers on the cards
... and even then, (if the customer is actually SGI themselves), you'd better cross your fingers, because SGI probably has a database of part#/serial# for support purposes, and all your serial#'s (the ABC123 thingie) would show up as V10 parts ...
IMHO there are less cumbersome ways to make a few bucks.
