Description
File: source:trunk/src/VBox/Devices/PC/BIOS/rombios.c
This is the same bug as bug ID #3170157 registered at the Bochs bug database on SourceForge. The equivalent Bochs source file is bochs/bios/rombios.c .
Just before the bios32_end label in rombios.c we have
mov ecx, #0
According to the specification this should be the length of the code/data segment used to access the service. It's definitely not supposed to be zero length. Given that the base specified in the line above is 0xF0000, this will provide a reasonable length value for now:
mov ecx, #0x10000
