Before you make bzdisk. Insert the floppy that you want to use as
bootdisk into the floppy drive.

This copies your kernel image directly onto the floppy, which then can
act as a linux boot disk.

512 is only the block size. If the kernel image is less than 1440 KbQuote:> > dd if=<kernel image> of=/dev/fd0 bs=512 conv=sync ; sync

I was trying to update a "live" file sys boot disk with a new kernel,
which I assume means you have to Lilo it before it will work. I copied
the vmlinux kenrel to the diskette, and tried Lilo a number of different
ways trying to get it to write to the diskette, but appparently failed.
It did however write to my hard disk, and trashed the the MBR. I got as
far as "LIL-". I booted a DOS disk and ran FDISK /MBR to restore the DOS
Now the question is: How do I reinstall Lilo into the MBR correctly?
My big problem is that I have no reliable boot floppy. The earlier ones
all have trouble recognizing my TMC850 SCSI controller on the sound
card, and lock up 99.9% of the time. The newer prebuilt ones won't
autodetect it it and furthermore ignore the Lilo line I usually use
"tmc8xx=0xde000,12" when I booted from the HD. They stop with a kernel
panic "can't mount root".
Next question: Once I've fixed the previous question, how do I correctly
update the kernel on a live boot floppy?
I've read the Linux Bible and FAQ's I could find, but did not see a
