Classic doesn't reach the flashing "?" point of boot
Posted by: netfreak on 2018-01-05 15:55:18
Got a Classic I wanted to try the ROM boot trick with so it has no internal hard drive installed. I noticed both before and after recapping the board it never reaches the blinking question mark point of the boot process. Basically only goes as far as having the mouse show up then just sits there (mouse still moves around). Tried it both with a good battery and without a battery, doing reboots after power applied, hitting various key combinations. The board looked good with no visible damage so I'm not sure what exactly is causing this. Any ideas?

Did you wash the mobo? Just asking.

Yeah after I had no other ideas I tried a full wash. Didn't help.

Check the scsi chip and the traces that connect it to other components. The system will exhibit this exact behavior when there’s a problem with onboard scsi.

Same with the SWIM.

Or occasionally, a bad hard drive.
