IRIX OEM gigabit cards command a premium online, often over $100USD. However, with a bit of engineering it's possible to modify cards using the Broadcom BCM5704 chipset to appear as SGI ethernet cards P/N 9210289.
To do so, install the card in a GNU/Linux machine with an open PCI-X slot, and use ethtool:
ethtool -E (interface) magic 0x669955aa offset 0xa4 value 0x80 ethtool -E (interface) magic 0x669955aa offset 0xa5 value 0x13 ethtool -E (interface) magic 0x669955aa offset 0xa6 value 0x10 ethtool -E (interface) magic 0x669955aa offset 0xa7 value 0xa9
This has been shown to work on the following cards:
- Alteon ACEnic 10/100/1000
- Compaq NC7770 Gigabit Server Adapter (With the Tigon3 chipset)
- 3Com 3C996 10/100/1000 PCI-X Server Network Interface Card (With the Tigon3 chipset)
- IBM NetXtreme 1000 T
