Wont matter if set to ide0 or other if he only has a sata drive, I think he needs a driver and floppy+F6 to even get windows onto the sata, cause he aint on xpsp2 slipstreamed with a nf4 chipset, if silicon or other he may well need the drivers 1st.
On another note I have read some here saying the NF4 mobos trick windows into seeing the controler as eide till you later get sata drivers installed, this is not true, you need XPSP2 on the cd slipstreamed, it wont work if its old XP or even XPSP1, in that case you need floppy +F6 as normal then you can install your service packs.
SP1 brought Sata support and SP2 brought native Sata support to some controlers not inc Silicon Image where you still need floppy +F6, this is/was same on Longhorn/Vista, although Vista has now added options for floppy/cdrom/usb device to menu.
