Users unable to write to mounted FAT32 partition

[Michael G.]

OK, I've scoured the archives for an answer with no results.  I'm 
sharing a FAT32 partition between XP and 6.2 Release.  The problem is I 
can mount the drive but only root can write to it (users can just 
read).  I have the following in fstab:

/dev/asd42        /mydos        msdosfs     rw  0 0

I've tried adding the -u or -g option with no luck.  I understand that 
since FAT has no inherent permissions chmod has no effect either (tried 
it just to be sure) so it must be set from fstab.  Any help?

Thanks!

M.G.
