mount_msdos problem

Post by Koling Chan » Sat, 07 Mar 1998 04:00:00



I have a dual boot machine with msdos and freebsd sharing one scsi hard
drive.
Whenever I tried to mount msdos partition in freebsd, the machine
encounters
problems and reboot. The command I used was.
mount_msdos /dev/sd0s1 /dos

This is my fstab file:

/dev/sd0s2b             none            swap    sw              0
0
/dev/sd0a               /               ufs     rw              1
1
/dev/sd0s2f             /usr            ufs     rw              2
2
/dev/sd0s2e             /var            ufs     rw              2
2
proc                    /proc           procfs  rw              0
0
/dev/cd0a               /cdrom          cd9660  ro,noauto       0
0
/dev/sd1e               /disk/d2p1      ufs     rw              2
2
/dev/sd1f               /disk/d2p2      ufs     rw              2
2
#/dev/sd0s1              /dos          msdos   rw              0       0

Can anyone give me a hint? Thanks.

Later I found that the filesystem I used for my dos partition (actually
windows 95) seems to be
a new one, message displayed by fdisk in freebsd:

The data for partition 1 is:
sysid 11,(Primary DOS or Windows 95 with 32 bit FAT)
    start 63, size 4449942 (2172 Meg), flag 0
        beg: cyl 0/ sector 1/ head 1;
        end: cyl 276/ sector 63/ head 254

It is different to someother systems that work:

The data for partition 1 is:
sysid 6,(Primary 'big' DOS (> 32MB))
    start 63, size 4192902 (2047 Meg), flag 0
        beg: cyl 0/ sector 1/ head 1;
        end: cyl 260/ sector 63/ head 254

Maybe this is what causing the problem?

Does FreeBSD support 32 bit FAT ?

FreeBSD doesnt support Fat32 (yet?? hopefully?)

FreeBSD-current has has support for FAT32.  However, I don't
know how robust it is, nor do I know if FAT32 support will be
pulled into the upcoming 2.2.6 release.

There is support for VFAT (I'm not sure about FAT32) in -current. You can try
it using picobsd floppy - it was built right after this feature was added, so
it contains some known bugs, but most of the time it works ok. See
http://www.freebsd.org/~abial

1. Running but mount_msdos, ppp and Syncing disks problems

Hello List,

I'm up and running but somewhat "crippled".   I have several
outstanding problems that I haven't been able to solve.
Problems are on a P-100/32MB/NCR SCSI II/HDs 1.2Gig
and 1.0Gig.  DOS and Linux on SD0 and FreeBSD 2.1  on
SD1, partition 1 and Linux  /usr/remote on partition 2.
Booting all OSes from Lilo on SD0.

First: During reboot/halt, expected "syncing disks ... 3 3 done"
        message replaced with "syncing disks ... 1  1  1  1  1
        1  ...  1 (fills entire line) giving up" and then
        "Rebooting" which results in a dirty file system at
        each reboot.

Second: Cannot mount MSDOS patition from sd0.  I've tried
        mount_msdos /dev/sd0 /mnt   and various
        combinations around that without success.  Error
        msg = sd0: error reading primary partition table
        reading fsbn0 (sd0 bn 0; cn0 tn 0 sn 0) returned
        when using fdisk.
        /etc/sysconfig has device sd0 and drive is
        detected at boot time.  fdisk  

Third:  ppp returns error after dial command:
        "Cannot access modem"  or equivalent.  
        Occcasionally, it will work.  I have a symbolic link
        from modem to /dev/cuaa1 (my modem is on
        DOS COM2 port) in /dev directory.    Also have
        tun0 in /etc/netstart and /sys/i386/conf/MYHOST.

Fourth: About 50% of my kernel makes fail with Signal errors
        10 or 11 and kernel panic: vm_page_free freeing
        free page.  Don't see either problem making Linux
        kernels.  Haven't seen any other evidence of a
        memory problem in other DOS, Linux or FreeBSD
        activities.

Any suggestions and advice on additional documents to read
would be greatly appreciated.  I've read FAQ, handbook, and
info FreeBSD and linked web sites in addition to man pages.
