Re: Boot floppies of RC1 broken for VAIO laptop


I run

silverboxy:/home/rd# dd if=grub-0.97-i486-pc.ext2fs of=/dev/fd0 bs=512 
conv=sync ; sync
2880+0 records in
2880+0 records out
1474560 bytes transferred in 96.615515 seconds (15262 bytes/sec)

but the floppy did *not* boot. Is that one in etch broken, or did I do 
something stupid?

I copied on the same floppy super grub-disk sgd_0.9528_english_floppy.img. 
Booting with this one worked well.
