I'm trying to tri-boot windows, gentoo and freebsd 4.10 cause I don't have an extra HD but had an extra slice to install. the hd is a maxtor 40gb IDE, model# 4d040h2, labeled on it says: cyl 16383 / head 16 / sectors 63 / LBA 80043264 when I throw the first install cd in it says the drive geometry is (4982/16/63 80035830). I booted into gentoo and used "hdparm -g /dev/hda" which gave me 65535/16/63 = 80043264 and to be quite honest I've looked but cannot find out where to locate the BIOSs geometry but partition magic SEEMS to indicated physcial geometry of 4982/255/63. I tried to find information in the handbook about it but couldn't and a google for this is overwelming for a newbie and nothing specifically I can see about my drive geometry... /dev/ad0s1 --> WinXP /dev/ad0s2 --> Gentoo2004.1 /dev/ad0s3 --> ** FREEBSD ** /dev/ad0s4 --> EXTENDED /dev/ad0s5 --> FAT32 partition for downloading to on all OSs /dev/ad0s6 --> Linux SWAP I'm not sure which drive geometry I should be using, I've heard of issues installing freebsd causes problems with the geometry and using other os/utils (ghost/partition magic) afterwards. I do not want to lose anything on the drive! If I need the BIOSs geometry, I would appreciate a suggestion of a tool to find this out or can I trust the hdparm/partitionmagic? I would appreciate the help, Geoff
