Hi Mike-
I followed this method:
http://failverse.com/creating-a-non-standard-size-bootable-floppy-image-for-pxe-boot/
That worked, the rest was just making SeaBIOS (at the time) try to read
them, as per the discussion.
FWIW I managed to increase my ROM chip size from 8 to 16MB and stuff it
with
if the
requirements are documented...
Cheers,
Rafael

Hi,
I've built SeaBIOS 1.12.1 with coreboot for the Thinkpad X210 (51nb
aftermarket board).
Generally I can get into SeaBIOS itself just fine, but I haven't had
any luck loading much of anything besides Linux Live. Tianocore &
other payloads work just fine as far as I can tell.
I've prepared
Right, but I'm not building for OVMF, I'm making a Coreboot payload.
Does that option still exist there?

Hi all-
I've found only vague references to doing this (
https://www.seabios.org/Build_overview#Build_as_a_UEFI_Compatibility_Support_Module_.28CSM.29),
and no real guides / examples.
Before I go on a wild goose chase, has anyone tried this before?
I've tried the other way around, loading DUET

Thanks for the hints so far, either way!

FWIW, for my large floppy the size is detected correctly, as in the
following output:
"phys_alloc zone=0x07f41ea8 size=16777216 align =1000 ret=6f2f000
(detail=0x07f315b0)"
It LOOKS like it's also being assigned correctly...

Mike-
The print statements didn't really help too much (so far).
However, I did get a TINY bit further by playing with the disk geometry.
Now I get:
"Loading vmlinuz...CHS: Error 0101 reading sector 18277 (8/59/6)
Loading core.gz...CHS: Error 0101 reading sector 457 (0/16/1)
Booting kernel
is an ELF file, right?
How would that step go (vmlinuz -> ELF)?

Hi,
I'm working on stuffing a bootable Linux distro into coreboot. In QEMU I
already succeded by using coreboot's built-in kernel loading mechanism, but
that's without SeaBIOS.
I'd love to have it as a SeaBIOS payload so I can also boot other things,
but I guess I'd have to create a custom-sized
