My XP install finally broke beyond hope of repair, so I've decided to wipe it and go with mac.

The problem is I've tried several different installs, and nothing is working so far. iAtkos didn't even get past the "apple/pinwheel" loading screen. iDeneb installs fine, but it always hangs during boot.

I have an Acer ASE380-UD440A desktop, with the following specs:
CPU: 4400+ AMD Athlon 64 X2
Chipset: Acer EM61/EM61PM
Video: Nvidia GForce 6150SE nforce 430
RAM: 2GB DDR
HDD: 320GB SATA

I've tried installing with vanilla kernel, vanilla kernel with AMD fix, Voodoo Kernel, and all of these with/without the seemingly appropriate kexts for video,audio,etc...

Every time I install, I get the "no smoking sign" ("O" + "/") upon boot.
UPDATE: I tried booting in verbose mode, but I got "Still waiting for root device"
Safe mode doesn't work either

Should I try a different Kernel, or a different distro? Can anyone help me out?
