ab7371532f implemented hook_interrupt() in PCI code 
enabled PCI interrupts
ohci seems to damage something in PCI config -> PCI device enumeration 
does not top with latest device
networking in EmuTOS lost (probably a result of PCI interrupt
implementation)

e365f91254 networking works (sort of). For some reason, the Firebee packets don't cross my switch (or only very few of them do). If I put a Linux box in between (cross cable), using it as router, everything works flawlessly. 2014-01-06 18:44:36 +00:00

e5c9d63059 cleaned up. X86emu does not work with debug trace on currently. 2014-01-03 21:03:35 +00:00
