3c90x
3c556 NIC
The Card
The 3com 3c556 chipsets are somewhat compatible with 3c59x and 3c90x cards.
Programming considerations
- Scan the PCI bus for the device, 3com vendor id 0x10b7, 3c556 device id 0x6055.
- Follow the linux or any other driver.
- The ReadEeprom command value is 0x230 and not 0x80 as on 3c59x and 3c90x cards.
