10.5.8 installed on my iDeneb HP dc7800. At first I got the dreaded Still waiting for root device (which I'd got before with the initial install), but copying all the *ATA* extensions from my backup got me past that. Now though, PS/2 isn't working, and USB never worked for me so I can't log in and I'm a bit stuck! I tried copying my previous PS/2 kext into place (just the regular Apple one), but it didn't make a difference. Any suggestions? thanks!
