Hmmm... What happened now? A short time ago my second computer on which I tested the schedule things seemed to have switched on itself... or did i touch the keyboard? I normally switch it on using the Space key. I couldn't see anything because the monitor was switched off, and it wasn't booting the system, it was stuck in the first screen telling BIOS checksum error... After restoring the BIOS settings I booted in both systems I have installed (10.5.3 and 10.5.6), there wasn't set a time schedule... strange.

OK well I tried it...

BIOS Settings are still the same, and ALL works using Vanilla kernel (Darwin 9.7)!!

*Had to set time zone back 1 hr (to match the BIOS clock).

What amazes me is why Mac OS X can do this on a PC and Windows can't! IMO thats pretty impressive :)

Computer went to sleep, woke (even from full shutdown!) and everything else!

I use it to wake me up every morning :D

You also can't use 4 GB RAM with a standard 32-bit Windows, OSx86 is!

I have a hunch.
Note that everyone who has this working without BIOS checksum problems is using a Gigabyte board (sans one Asus). And notice how everyone with problems has an Asus (again, sans the lucky one).
Funny, isn't it. Coincidence? I think not.
Then again...SaCleoCheater, what mobo are you using?
