Hi, i'm new here.. i'm still downloading

oh yeah.. about the sb600, i guess you can set AHCI mode in the bios.. it should work fine, once mac installed you can load the sb600 kext. it works for me with 10.5.1 ( only with SATA hard drive pair with SATA DVD drive )
since i upgraded to phenom, i havent try updating to 10.5.2 or 10.5.3
guess i'm gonna try the lawlessppc's 10.5.4 now ;p
my system is:
MSI K9A2 Platinum V1
AMD Phenom 9550
ATI 3850 512 mb
2 gb DDR2
