win2k server only showing 131gb out of 250gb

[Ob1]

i have a WD 250gb drive connected to an ide cable on a 1u server. im installing win2k server with sp4. when i boot to the cd i am only seeing 131gb worth of storage space. when i enter the bios it shows the 250gb hard drive. i threw win xp pro in and booted to it to see if i got the same results. instead it shows the whole amount of the drive (233gb roughly). i thought sp3 or sp4 was suppose to address the 48bit lBA problem.

does anyone have any suggestions as to y its not showing my the full drive capacity when booting to my w2k server with sp4 cd? and any solutions to this problem would be appreciated.

server specs:
intel SE7501 CW2 motherboard
dual intel xeon 2.4ghz processors
2gb total (512mb in each dimm slot)
currently 1 WD 250gb IDE hard drive, adding a second one to setup RAID 1 just as soon as it comes in
dual onboard nic/video

thanks

update:
fixed it.
i had to add a registry key for 48bit LBA in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Atapi\Parameters

On the Edit menu, click Add Value, and then add the following registry value:
Value name: EnableBigLba
Data type: REG_DWORD
Value data: 0x1

reboot machine.

sorry for the double post
