Earlier, I posted about a problem I had with three 3400 motherboards:
-----
I have three 3400 motherboards exhibiting odd problems. Each of the three behaves the same: It can boot, it gets to the flashing disk, and goes no further (HD or CD ROM). Oddly enough, neither the trackpad, nor an external mouse can get the cursor to move, but it accepts keyboard commands, such as power on, and PRAM zap. I tried Open Firmware but nothing happens.
I replaced the PMU chip on one with an identical part # PMU from a 5300, but nothing changed (same as it was before).
-----
SInce that time, someone suggested that I try a boot floppy. I tried an OS 8 boot floppy, and it boots ! However, the cursor still wont move.
What does this tell me ? Is the IDE controller IC is toast ?
