I put three 12.0 GB Quantum Bigfoot TX IDE drives on my freeBSD 2.2.5 
machine, and BIOS correctly identifies the drives as 12 GB, but freeBSD 
thinks they are only 8.4 GB:

	BIOS (LBA Mode ON): 23,361 cyl / 16 heads / 63 sectors per track   

		==> 23,547,888 sectors (X 512 bytes/sec = 12.0 GB)

	freeBSD FDISK shows: 1078 cyl / 243 heads / 63 sec per track   

		==> 16,503,102 sectors (X 512 bytes/sec = 8.4 GB)

When I manually enter the correct geometry into FDISK (23361/16/63), it 
correctly computes the number of sectors for 12 GIG (23,547,888), but 
unfortunately still behaves as though there were no more than 8.4 GIG 
available --- the (C)reate option maxes out at 16514001 sectors.

Is freeBSD actually limited to 8.4 GIGs per IDE drive?
=====================================================

P.S. These 12 GIG drives only cost $80 more than their 8 GIG 
counterparts, so its not the end of the world if 8 GIGs is the 
limit. Still, having the extra space would be awesome... :)  :)

Best wishes,
