[advancemame-users] makebootfat corrupting fat filesystem

[LCID F. <lci...@gm...>]

Hi.
I attemted to create a (1GB) bootable USB disk via makebootfat and
failed miserably. I formatted the disk with mkfs.vfat and then executed
 "sudo ./makebootfat -v -o /dev/sde1 -E 255 -1 fat12.bin -2 fat16.bin -3
fat32lba.bin -m mbr.bin" root on it (like it is describen on various
websites). The result is that the disk is no longer mountable.

Using the FreeDos mbr.bin attemting to mount I get:
FAT: invalid media value (0x06)
VFS: Can't find a valid FAT filesystem on dev sde1.

Using mbrfat.bin mount complains:
FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev sde1.

So am I doing anything wrong?
Looking in the forums I wonder - is this software still supposed to work?
