[realtek] strange behaviour of rtl8139 card

[Pawel]

Hi

I bought ethernet card with 8139 chip (digitus DN-1001)
I have inserted it into pci slot and turn my linux on (red hat 7.1,
kernel 2.4.3) and then compiled driver (rtl8139.c) from scyld site and 
inserted the driver into kernel. Whats the problem ?
card was working properly but very slow. It lost about 60% IP datagrams.
But thats not all. I restarted my computer and turn on windows 2000, then
loaded driver from diskette and... the card was working perfectly.
So I restarted my computer again, turn on the linux, inserted driver(the 
same as before) and ... card was working perfectly !?!
isn't it strange?

But when I removed the card from computer and later inserted it back.
i had to start windows again, because of the same problem.

these are registers before i started win2k:

./rtl8139-diag -a

Index #1: Found a RealTek RTL8139 adapter at 0xd800.
The RealTek chip appears to be active, so some registers will not be read.
To see all register values use the '-f' flag.

 The chip configuration is 0x10 0x6d, MII full-duplex mode.

and these are after, (and now card works ok)

I'd like to know
1) change of which registers has solved the problem ?
2) there's a lot of registers in the rtl8139 specification (which i've
downloaded from realtek). How to find the descriptions of registers which 
are printed by rtl8139-diag program ?
3) what do I have to do if i don't want to start windows after inserting
this card to my computer.(how to configure it under linux)

I'll be very grateful for help
