I haven't gotten around to poking at SeaBIOS yet, I'm still wondering how to test my large floppies.
Syslinux appears to install to them fine, but QEMU doesn't seem to like booting them with -fda.
Do you guys have any suggestions on how to test booting the large floppy images?

Personally I think that either this guy did something incorrectly or there's a Windows 3.1 bug. Meanwhile, Rafael's Linux-based OS is going to boot from this floppy like it's a ramdisk, so hopefully should be indifferent to the custom floppy sizes and would work. I share the same hopes for KolibriOS: although its' 1.44MB floppy contains really a LOT of stuff, some cool things like console emulators didn't fit - so I'm going to create the extended Kolibri floppy version, which will be either 2.88MB or some custom ( 1.44MB * X ) size.

Hi, I'm working on stuffing a bootable Linux distro into coreboot. In
already succeded by using coreboot's built-in kernel loading
that's without SeaBIOS.
I'd love to have it as a SeaBIOS payload so I can also boot other
but I guess I'd have to create a custom-sized floppy image for this or figure out how to create an ELF payload out of a Linux kernel (I'm
either, but I wasn't able to find any documentation on the ELF method).
The guy who put Win 3.1 in coreboot attempted the floppy method, but according to his article he did not find success with this method due
unknown and complex issues in the floppy-side logic of SeaBIOS.
So, I'm making the question explicit: What would it take to support custom-sized floppy images? In particular, I'm thinking of a 16MB
My vague recollection is that various OSes had hard coded expectations on the types of floppy drives supported. I did not think it would be easy to support a floppy size larger than 2.8MB.
It is possible to emulate a hard drive in memory. However, that would require code changes.
