3c90x NIC
This page is about the 3c90x/3c90xB/3c90xC family of ethernet adaptors manufactured by 3com. A number of 3com cards share the programming interface of this family; this includes the 3c556 10/100LAN + 56k Modem MiniPCI adapter (also known as 3CN3AC1556B and 3Com® Megahertz® 10 Mbps LAN CF+ Card) and 3c555 10/100LAN MiniPCI adapters.
The Card
3c90x is a successor to 3c59x (which are successor to 3c5x9). A new feature introduced in this series is full bus master operation mode with seperate download and upload buffer chains.
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.
