Hi everyone, I know similar problems have been discussed in this and other forums, but I can't seem to find a working solution. Let me first start in giving the specs of the system I bought: - Gigabyte GA-K8NF9 Ultra Mobo with nForce4 Ultra Chipset (http://www.giga-byte.com/MotherBoard/Products/Products_GA-K8NF9 Ultra.htm) - AMD Athlon64 3200+ Venice core - 1Gb Kingston DDR Dual Channel - ASUS EN6600SIL/TD 128Mb - Western Digital 160 Gb SATA-II (WD1600JS) - NEC ND4550 Dual-layer DVD - NEC Floppy-drive The problem is that on installation of windows XP Home Edition (incl. SP1A) the hard disk isn't reecognized and therefore setup is closed. I've already tried installing both the nForce4 SATA driver provided by Gigabyte and the SI3112 SATA drivers provided by Western Digital through the F6 pre-install. I also checked if SATA was enabled in the bios. Right now, I'm at a loss on how to continue... Can anyone help me with this?
