Geez... I've got 4 gigs and that's over kill for my uses... but then I don't run memory intesnsive programs like Microsoft produces... > In addition, Partition Magic indicates that the geometry of > the drive is 2055 cyls, 255 hds, 63 sects. > > During FreeBSD bootup, it correctly identified the drive, but > incorrectly reported that there is 16383 cyls, 16 hds, 63 sects, 512 b/s, > and a total of 8063MB in 16514064 sectors. Actually, it's more like Partition Magic incorrectly reported the geometry, while FreeBSD correclty reported it. Hard Drives over 8 gigs actually violate the EIDE standards so manufactures have been putting BIOS chips on the drives to fool the computer into using the extra space by misreporting the actual geometry of the drive. I belive that FreeBSD (correctly) actually goes out and looks at the physical size of the drive. > I am wondering if anybody has gotten FreeBSD to see the whole > drive and properly install FreeBSD onto the system. I belive that 2.2.7 or 3.0 see drives over 8 gigs as they had to rewrite the driver and dumb it down to be able to see these drives. Now... if you had a 16 gig SCSI drive....
