Hello,
I recently bought a new machine with this fast ethernet card.
Everytime when the driver is loaded, the link went down to 10mbps, as
my hup shows me this.
The driver update to version 0.99G didn't help, but after getting deeper into
it I recognized that it could be a timing problem, so I changed the wait
time:

29a30
>
467c468
<   { "100baseTX", Media_Lnk, 0x02, XCVR_100baseFx, (14*HZ)/10},
---
>   { "100baseTX", Media_Lnk, 0x02, XCVR_100baseFx, (40*HZ)/10}, 

The 40 was just my first guess and it helped. Question to the developer:
Is this value reasonable ? What impact has it on other functions ? Should I
decrease it again to get as low as possible?

Is it possible, that the speed of the machine has an impact on the timing
100MHz bus, 450 MHz PII ?

AFAIK it's quit stable now, I did some transfers between my computers with
big files (140MB) without problems.
