Hi. I try set floppy support in SeaBIOS like this:
 
root@debian:~# cd /coreboot
root@debian:/coreboot# ./build/seabios/scripts/encodeint.py floppy0 4
root@debian:/coreboot# ./build/cbfstool build/coreboot.rom add -f floppy0 -n etc/floppy0 -t raw
root@debian:/coreboot# ./build/cbfstool build/coreboot.rom print
coreboot.rom: 256 kB, bootblocksize 848, romsize 262144, offset 0x0
alignment: 64 bytes
=================================================
Name                           Offset     Type         Size
fallback/romstage              0x0        stage        17988
fallback/coreboot_ram          0x4680     stage        105981
fallback/payload               0x1e4c0    payload      59988
pci10ec,8139.rom               0x2cf80    raw          57344
etc/floppy0                    0x3afc0    raw          8

After PC boot, press F12 and have menu:
 
Press F12 for boot menu.
 
Select boot device:
 
1. Floppy [drive A]
2. DVD/CD [ata1-0: OEM     CD-ROM F563E ATAPI-0 DVD/CD]
3. ata0-0: Maxtor 2F020J0 ATA-7 Hard-Disk (19881 MiBytes)
4. gPXE (PCI 00:11.0)
 
but after press 1 boot from floppy not working (FDD LED not light) and:
 
Boot failed: could not read the boot disk
 
I tray boot from Win95 boot floppy disk. In CMOS is set FDD 3.5' 1.44MB.
In WinXP FDD read OK floppy content but after restart not possible copy any files from floppy. Also after restart I press F12 and select 1. Floppy [drive A]. Now FDD LED light but errors:
 
Disk I/O error
Replace the disk, and then press any key
 
In terminal over COM:
 
floppy error: 40 04 10 01 00 00 02
 
Please see winxp_restart.log
 
I tray also boot from other floppy gPXE 5.4.4 and have other errors:
