Power Macintosh B&W sits in gray screen.

Submitted by DaveyPocket on October 4, 2007 - 10:50pm. PowerPC Macs

Whenever I turn on my B&W G3, all it does is start up, and sit in a blank gray screen, no cursor, no nothing. I think it's because I accidentally selected network boot and it's trying to find a network to boot off of. Is there a way I can reset the Macintosh's boot settings? If you have info, please tell me. Thank you.

Hold em then power it on, let it bong a few times, let 'em go.
Alternatively there are Open Firmware commands you can use, but I dont remember them specifically.

If that doesnt work out, there's the CUDA reset on the motherboard. Google CUDA B&W, CUDA Power Macintosh G3 for pictures et cetera.

sifting

If you go into firmware, and type "sifting ", then whatever part of a word you're looking for it will list the commands with that word in it (i.e. "sifting boot" should show, a list of commands with boot in the name, including mac-boot, which is the standard boot command).

reset-all, reset-nvram, set-defaults, and sync-nvram are all some words I've gotten some use from in the past.

I got it, booted directly from Mac OS X when I typed in "boot". Thanks for your help.
