I just put a 20 gig hard drive on an asus p3b-f motherboard and it reports
that the size is only 8 gigs.
Actually, it says in the bios:
CHS capacity 8422 mb
max LBA capacity 20496 mb

Can anyone please advise what I need to do to have the whole drive size
recognized?
I also wanted to install an 80 gig hard drive on the system, but I'm holding
off until I get this problem resolved.
Thanks for any help.
 
If Logical Block Addressing is enable it will operate as a 20 GB drive. If LBA is not enabled then Cylinder Head Sector addressing will see 1024 cylinders (about 8 GB). You might need a BIOS update. Most likely if LBA is enabled you will be able to use a drive up to 128 GB.
