Did this exact thing yesterday on an 80g Sata + Gigabyte Board..........
What I had to do was partion the H/Drive first, I use F/Disk.
Format in this case 2 partitions.
I was booting from a CD Rom to install Op/Sys (Windows Xp Pro).
As soon as the VERY FIRST Blue screen appeared insert the sata drivers which were on Floppy disk.
The Windows Op/Sys then took over and loaded the Sata drivers in as the Windows files were being loaded.
Worked perfectly first time.
