NIC Cards

[OOzy Pal]

My card is built-in my motherboard is a Gigabyte 915G (81915G Duo).
The built-in NIC is NetLink BCM5789 Gigabit Ethernet PCI Express.

I have few questions?

1. Anybody know if this NIC compatible with Ubuntu?
2. This card is 10/100/1000 and I have 256K DSL? Does it make a
difference if I switch to one of the 10/100 NIC?
3. If item 1 above is OK, how can I install this NIC?


Thank you.
