Hi Kelly, > I find it hard to believe that a 3 line patch would > be enought to enumerate the partitions inside extended partitions, must less > with arbitrary depth. But I've been amazed before :) It's probably not really what you expect (or hope? for), and not that much of a deal (less than a mouse driver ;) ). I was just wondering where to post these kind of things. The only thing the patch does is make the linux extended partition type known and use it when available. > > I would like to submit a (three line) patch to enable the use of linux > > extended filesystem. I mean using as in mounting, not running from. The linux extended partition is just a dos extended partition with a different identifier (0x85 instead of 0x05). You can use it as an extra extended partition, without dos being upset about seeing another extended partition. I actually use it on a multi os machine which bios doesn't understand the 20G hd. (Dos, dos extended containing ia linux /boot, ufs 44bsd, linux extended.) Here comes the patch (for 4.0R): /sys/kern/subr_diskmbr.c Insert after line 51: #define DOSPTYP_LINUXEXTENDED 133 Insert at line 347 (original offset), before the closing bracket: || sp->ds_type == DOSPTYP_LINUXEXTENDED Insert at line 437, before closing bracket: || dp->dp_type == DOSPTYP_LINUXEXTENDED That's all there is to it. I'm not sure the existing code handles dos extended LBA partitions, or needs modification for this, so I didn't include it. You could try to add a DOSPTYP_EXTENDED_LBA (0x0F). Haven't tried. Might go seriously wrong. To make things comeplete you could also modify fdisk. /usr/src/sbin/i386/fdisk/fdisk.c Insert after line 166: ,{0x85, "Extended Linux"} Using two extended partitions you might want to increase MAXPARTITIONS in /sys/i386/boot/dosboot/disklabe.h, /sys/sys/diskslice.h and /sys/sys/disklabel.h. Haven't really tested this thoroughly, but it seems to run fine. Ciao, Leonard. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
