Boot Floppy

Boot Floppy

[Koichi Sato]

I tried to make a boot floppy under DOS.
Initializes floppy and write a "boot.img" by "RAWRITE.EXE". or
make a boot floppy under UNIX with "fdformat" and "dd"

Then I boot a ULTRA30(Creater3D) with  the both floppy.
But I can not booting.
messages:
    Bad Magic Number in label block




Why??

No SMCC UltraSPARC machines are able to boot floppy AFAIK (only UltraAX/AXi
handle it).

Ray,

Thanks, but no progress yet. I used dd to copy to an unmounted
ext2-formatted floppy the files created by mkbootdisk: boot.msg,
initrd.msg, ldlinux.sys, syslinux.cfg, and vmlinuz. I also copied lsh
(Little Shell, which I can run and get a "C" type prompt). The
syslinux.cfg files was edited as follows:

label linux
	kernel vmlinuz
	append initrd=initrd.img root=/dev/fd0 init=/lsh

I stuck the diskette into a (SCSI) Windows machine, and after the
machine's SCCI BIOS loaded, the diskette is accessed and I get:

Loading.......................................................
Unpacking. Loading kernel

Hoever, instead of starting lsh, it simply resets the machine and I'm
in a boot loop.

Since runing ./lsh does lead to a prompt, I assume that binary is
workable. Therefore, something may be wrong with the script
above. I don't understand init, but why the forward slash in
init=/lsh?
