hi everyone,
having a bit of a weird problem here that i'm getting stumped with. I have a beige g3 minitower which ive been trying to get back to life... had this thing since 2001. Currently, everything is working fine except firewire and usb cards. Ive also got two motherboards, and the behavior is present on both. I should add, I am using a PC power supply, with the jumper set to PS2 on the g3 motherboard. The machine is working fine with other cards, presently an acard 6260m and ati 9250 graphics. Its running a Rev. B ROM. Ive got an intel 40gb ssd with sata/pata adapter running the OS, which is 9.2.2, which boots off the Acard. The drive was cloned over from my beastmode MDD.
The cards *do* appear in system profiler under PCI cards, but there's no USB or Firewire bus shown, and plugging in devices has no effect. Ive plugged in flash drives, keyboards, mice, wifi adapters and none of them seem to get any power, even though the cards ive tried (adaptec 3020 and a siig combo) are both connected to power via molex. the system extensions for usb and firewire are present and enabled according to extensions manager. ive tried both cards in my MDD and my Gigabit G4 and they work fine in those systems. board and pram resets have no effect.
kind of running into a brick wall here repeatedly now for a couple weeks trying to figure out what's wrong here. does anyone have any suggestions? could the fact im using a PC power supply be causing it? unfortunately I dont have the original PSU anymore, at least, I dont think I do. But if the system is working fine otherwise what difference should it make? Should I just look at replacing the logic board?
Thanks for any tips or suggestions anyone might have.
