5 out of 5 eggsYes a cheap card that works

Pros: 1 Gb connection. Works with other variations of the Youkon chipset driver. Zero issues in XP.

Cons: None

Other Thoughts: I did download another vendor's drivers after reading not to use the ones on the CD. Install was fast and flawless. Off loading the network processing made a noticeable improvement in my PC's speed.

2 out of 5 eggsMay require newer Linux drivers

Pros: Small, inexpensive, includes half-height PCI bracket.

Should be a nice card with a newer, working driver. Linux 2.6.24 or newer might work.

Cons: Did not work with Linux 2.6.18 or 2.6.22 on Debian/testing AMD64, or Ubuntu gutsy (7.10) AMD64. It could not establish a link or transfer any data.

On boot, the driver reports:
sky2 0000:03:00.0: error interrupt status=0x80000000
sky2 0000:03:00.0: PCI hardware error (0x2010)

Then it loops through this forever:
sky2 eth0: hung mac 0:68 fifo 143 (133:76)
sky2 eth0: receiver hang detected
sky2 eth0: disabling interface
sky2 eth0: enabling interface
sky2 eth0: Link is up at 1000 Mbps, full duplex, flow control rx
sky2 eth0: hung mac 0:125 fifo 195 (93:88)

Other Thoughts: NOT identical to older Marvell cards. This "rev 2" chip fails but I hear the "rev 1" chip works fine.

sky2 0000:03:00.0: v1.18 addr 0xdbffc000 irq 18 Yukon-EC (0xb6) rev 2

5 out of 5 eggsidentical to other marvell chipset pci-e

Pros: same as pen120 which is known to work well with linux.

same as r*sew*ll board (even looks 100% the same).

both use 'sky2' linux driver.

Cons: n/a
