This has been a problem for long long time. If you tell the system a device is present when it isn't and it hangs on you, you shouldn't be surprised. I'm not sure what all the IRQ 15 stuff is about; that shouldn't make a difference. -- | Matthew N.

If irq for 3c509 board is set to 15, the board will not be configured, and system will boot with ep0 (but some ti{0-1} are up). If irq for 3c509 board is set to non-15, and ie0, fe0, le0, cs0, lnc0 and sn0 are enabled, system will hang as soon as it detects the ep0. This has been a problem for long long time. If irq for 3c509 board is set to non-15, and ie0, fe0, le0, cs0, lnc0 and sn0 are disabled; or set 3c509 board to PNP, system will panic, once the ep0 is configured. How-To-Repeat: Boot installation floppies and may sure to set 3c509 able to be configured, then it wil panic.
