The PC already has Linux, DOS 6, and Windows NT installed. The pqmagict.exe shows there are three primary partitions available and their sizes are 31.3MB, 4769.2MB, and 1349.2MB respectively. The first two are also shown in the DOS fdisk command. The second primary partition contains 7 subpartition: 4 labeled as Linux Ext2, 2 labeled as Linux swap, and 1 labeled as NTFS (I guess this is for Windows NT). I insert CD-ROM and reboot from it. At the FDISK screen, I see four entries: offset size end name ptype desc subtype 0 63 62 - 6 unused 63 64197 64259 wd0s1 2 fat 4 <-- DOS 64260 9767520 9831779 wd0s2 4 extended 5 <-- extended primary 9831780 2363180 12594959 wd0s3 3 freebsd 165 CA My question is: How come FreeBSD regard the first entry as unused? Why Partition Magic does not show this entry (It only shows the last three, wd0s1-wd0s3)? Why there are FOUR entries instead of THREE entries (each represent a primary partition)? Where does the extra entry (first one) come from? By the way, I installed FreeBSD on another PC successfully and devoted ALL disk space to FreeBSD on that machine. Still, I got the mysterious first entry labeled as unused. I read in an installation tutorial that it is for boot sectors. But for this PC, where can we find those 62 sectors that seems to be required by FreeBSD? Maybe I have to install FreeBSD FIRST (before other OSs) to make sure FreeBSD can use the first 62 sectors. I try to find the start sector of the DOS partition to see if there is any conflict, but Partition Magic has no such information for the first active DOS partition (I can get similar information on other partitions). Anyway, I install FreeBSD on the last partition "successfully" and reboot. The System Commander does find the FreeBSD partition. But when I try to boot from it. It says "read error" and the system halts. Any idea? Thanks for you help. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
