Tweak Intel21041 NIC?

[dbarrow]

Has anyone tried tweaking the NIC going to the cable modem?
I have an Intel 21401 10baseT
Noticed in PROPERTIES\ADVANCED there are several options to change:
Extra receive buffers (default =16)
Receive buffers (default =16)
Transmit threshold (default=96 bytes)
Process transmit first (enable/disable)
Anyone toy with changing these?
BTW: I use the Irq=4096 trick to add 4 meg buffer to the card in system.ini, it does work
My record PEAK throughput 4560.1Kbps

I use 6120 to my nic which is 5 megs works a lot better. ;) I have always use this setting sense I got cable 4 1/2 years ago. The man who installed my cable put this in. My speeds are great. ;)
