I have just built the Shuttle XPC SB81P (1st time) with following options:

6.00 PG (7-4-2005)
Pentium 4 540J 3.2GHz 800FSB LGA 775
Geil 1Gb PC3200 Dual Channel DDR Kit (2x512MB)
200GB Seagate Barracuda SATA-150 7200rpm
NEC 3520
Windows XP Pro SP1

I installed the raid driver (with AHCI in Bios) before XP installation and then formatted (NTFS) the 200GB Seagate Barracuda SATA-150 7200rpm as boot drive at C:.

Everything works absolutely fine, however at boot up screen, it shows me that the hard drive is LBA, ATA 100, 200GB. The problem is why isn't it SATA-150??

I am afraid that I do not use the hard disk at its full potential, please help.
Many thanks
