Hi all I have a Genius Hub Card (basically an Ethernet NIC that also acts as a four port hub). I would ideally like to use this card in an old 486DX4 machine which acts as a ppp router. The card is detected (under both Windoze and FreeBSD) as a RealTek card (the model number escapes me right now). I installed 4.0-R on this machine, which detects the card, but gives me "ed0: device timeout" messages. Usually this is because the interrupt is misconfigured, but I don't think that is the case here. As I was under time pressure, I pulled the card out and put it in a different machine, this one a P166 which works fine (with the same IRQ). Anyway, when I get a chance I would like to try it again in the 486. The 486 has three PCI slots, and the BIOS has some additional settings which may be the reason it wasn't working. I'm unfamiliar with what some of these do, and am hoping that someone on the list may have experience with early days of PCI and Plug 'n Play, and be able to help. These are the settings: Slot n IRQ Line (this is the only one I set on my first attempt, to 12) Slot n Latency Timer (ranges from 0..255 PCICLK) (was on 255) On Board PCI/SCSI BIOS Enabled/Disabled (was disabled) CC State Machine: Data Write 0 WS Enabled/Disabled (was disabled) Data Read 0 WS Enabled/Disabled (was disabled) Perhaps all I need to do is toggle the PnP BIOS setting, but before I pull out the screwdrivers and tear the two machines apart again, I'm hoping to draw on someone else's experience here. Any ideas?
