i hope you created it with dd/rawrite and did not just copy root.bin on

i can't imagine that this is really necessary. have you tried different
floppies ? - they are an extremely unreliable medium... maybe you should
even try to d/l the image again - there could have been some error during 
downloading it.

of course you can't mount these floppys as ext2 (or any other fs) - they
just contain an image (or, in the case of root.bin, a compressed image)
of a filesystem.
if you have the loop-device compiled in your kernel, you can mount the 
images in the following way:

mount -o loop rescue.bin /mnt  


mv root.bin root.bin.gz;gunzip root.bin.gz;mount -o loop root.bin /mnt

btw, syslinux.cfg is in rescue.bin ...

hope that helps,
