semi-ot: sis900 lan support

[Alessio Sangalli]

Hi. I've experienced some problems with sis900 ethernet performances. 
Though this is not *directly* linuxbios related, I think here I can find 
interesteds people.

I'm here with my pcchips 810 motherboard, but I've found the same 
problem on other TWO motheboards.

I load the sis900 module or I compile it into the kernel, but the 
performances are incredibly low: if I transfer a huge file, the transfer 
starts at 5MB/s more or less, but after few seconds it drammatically 
drops to 60KB/s. I would need more that two hours to transfer an ISO image.

I've changed the cable, connected the computers with a cross cable, but 
the problem is always there. The other computer has a rtl8139 card and 
works fine with other non-sis900 hosts. ifconfig or iptraf show NO 
errors but the transfer rate is no more than 60KB/s.

I'm using kernel 2.4.20, pcchips810lmr with 256MB memory and athlon2000+...

bye bye, thank you

I tried a 954MB (ls -lh) file on pcchips 787cl+ (sis900, via C3, 320Mb 
ram), and it took 22:20 using scp, no compression.  Since I have a 
10baseT network, using ssh, and other traffic, this seems about right 
(700+ kb/sec).  Kernel is 2.4.18, sis900 driver v1.08.02.

Is it possible to force the network at 10Mbps even if there is a 100Mbps 
capable cable?

Sure: mii-tool -F 10baseT-HD eth0
(for half duplex)

mii-tool -h for more options.
