I have a generic RTL8139C PCI Ethernet card which works fine in Win98SE with Realtek's drivers (just using the .inf, not installing any fancy managers, etc.), but is very unreliable when I reboot into MS-DOS Mode, use the F8 'Command Prompt Only' option, or use MS-DOS 6.22 proper.
I have the RTSPKT.COM driver and I'm using the MTCP suite. DHCP is failing saying there's no response. PKTTOOL says that packets are being sent, but none are being received. The lights on the back of the card are off. When RTSPKT starts, it incorrectly detects the link type and speed (should be 100Mbps full duplex I believe) in the intro text.
Sometimes this card will work (Act and Link lights on, all transfers working as expected) after removing the PCI cards from the motherboard and reinserting them in a different order, which makes me think it's a resource allocation thing? It's possible that this motherboard, processor and card combination just doesn't work with the way DOS works, but that's a vague conclusion.
Does anybody else have issues with this chip in DOS? Is there anything I ought to check in the BIOS or elsewhere to try to get this card working in DOS?
