I did a log but I think that there is nothing interesting to put the full log. I put the same end of the log boot from a floppy image and floppy disk.

Recently i make full access for flashrom and now possible flash bios coreboot or vendor bios from linux. After flash vendor BIOS or coreboot bios I noticed problems with timeout while load file pxelinux.0 over gPXE from TFTP server. To reslove this problem after flash vendor bios I need go to CMOS Setup (Del) and load defaults settings. To resolve problem after flash coreboot I need clear CMOS with jumper on board. After clear CMOS have not set RTC date and time and Debian-live over PXE not boot and have error Authentication error, '...respawning too fast: disable for 5 minutes'. This is only from Debian-live over PXE. The same Debian-live from CD boot ok. Also Debian installed on HDD boot OK. After set date and time in debian HDD like this:
date -s 2013-12-28 date -s 19:00
and reboot to debian-live from PXE the problem was gone and Debian boot OK.
I think the problem floppy error is related to the network adapter and timeout. This is not SeaBIOS fault.
