• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Luke Tanabay 2004-10-25 09:47:31 UTC]

When i try ti mount an dos floopy image i have a problem in kernel versin 2.6.9 and 2.6.9. I have not this problem with 2.6.7

mount -t msdos -o loop /opt/mkcdrec-8.2/tmp/bootflop.img /mnt/cdrom/
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       or too many mounted file systems
       (could this be the IDE device where you in fact use
       ide-scsi so that sr0 or sda or so is needed?)

I have compiled loop and ms dos in my kernel 

lsmod

Do any error messages appear in dmesg after attempting to mount?

[Comment 5 Luke Tanabay 2004-10-28 03:45:51 UTC]

Hi,

Yes I have a message in dmesg

loop: loaded (max 8 devices)
Unable to load NLS charset cp437
FAT: codepage cp437 not found

In my .config I have :

CONFIG_FAT_DEFAULT_CODEPAGE=437
# CONFIG_NLS_CODEPAGE_437 is not set

[Comment 6 Daniel Drake (RETIRED) 2004-10-28 07:47:34 UTC]

Ok, you should either choose a new default or enable that charset in the kernel config. Please reopen if that doesn't help.
