There have been success reports with SeaBIOS booting Windows 8, so
it's not a general win8 problem.

If possible, try to pull the disk image into a QEMU VM and see if it
has the same crash when running QEMU with a native instance of
SeaBIOS.

Also, make sure the problem is still present with SeaBIOS debug level
1 - very high debug levels are known to cause issues with some
software.

for sure - no issues booting Win8/8.1/10TP on the Haswell ChromeOS devices using SeaBIOS 1.8.0
