/* Set CONFIG_YABEL_DEBUG_FLAGS is a binary switch that allows you
* to select the following items to debug. 1=on 0=off. After you
* decide what you want to debug create the binary value, convert to hex
* and set the Option (Ex. CONFIG_YABEL_DEBUG_FLAGS = 0x31FF //Debug All).
*
* |-DEBUG_JMP - print info about JMP and RETF opcodes from x86emu
* ||-DEBUG_TRACE_X86EMU - print _all_ opcodes that are executed by x86emu (WARNING: this will produce a LOT of output)
* |||-Currently unused
* ||||-Currently unused
* |||||-Currently unused
* ||||||-DEBUG_PNP - Print Plug And Play access made by option rom
* |||||||-DEBUG_DISK - Print Disk I/O related messages, currently unused
* ||||||||-DEBUG_PMM - Print messages related to POST Memory Manager (PMM)
* |||||||||-DEBUG_VBE - Print messages related to VESA BIOS Extension (VBE) functions
* ||||||||||-DEBUG_PRINT_INT10 - let INT10 (i.e. character output) calls print messages to Debug output
* |||||||||||-DEBUG_INTR - Print messages related to interrupt handling
* ||||||||||||-DEBUG_CHECK_VMEM_ACCESS - Print messages related to accesse to certain areas of the virtual Memory (e.g. BDA (BIOS Data Area) or Interrupt Vectors)
* |||||||||||||-DEBUG_MEM - Print memory access made by option rom (NOTE: this also includes accesses to fetch instructions)
* ||||||||||||||-DEBUG_IO - Print I/O access made by option rom
* 11000111111111 - Max Binary Value, Debug All (WARNING: - This could run for hours)
