Hi,
I'm running centos5.2 on an Asus Vintage AE which has an integrated ethernet adapter based on the sis190 chipset. I had problems with older centos releases, but since 5.1 this network adapter is recognized and working properly with the stock sis190 driver. However it only works at 100mbps.
Asus product specifications claim it is a gigabit ethernet adapter. However at some web pages I read that the 190 is only fast and 191 is giga (which maybe wrong).
So does the sis190 chipset really support gigabit mode? Is this a driver issue or the adapter is actually just fast ethernet and asus is cheating? (Note that the sis190 driver also states that the 190 is a gigabit adapter). And if it is gigabit, where can I find a linux driver actually working at 1000mbps?
I tried booting with a fedora 10 beta live cd (to see if more recent drivers work at 1gb) but it runs at only 100mb too.
