(Table C0006)
Values for Reset Code / Shutdown Status Byte:
 00h-03h perform power-on reset
   00h	software reset or unexpected reset
   01h	reset after memory size check in real/virtual mode
	(or: chip set initialization for real mode reentry)
   02h	reset after successful memory test in real/virtual mode
   03h	reset after failed memory test in real/virtual mode
 04h	INT 19h reboot
 05h	flush keyboard (issue EOI(End of Interrupt) A particular command sent to the interrupt controller to indicate that the interrupt has been handled by software and that new interrupts of the same or lower priority may now be signalled by the interrupt controller.) and jump via 40h:0067h
 06h	reset (after successful test in virtual mode)
	(or: jump via 40h:0067h without EOI(End of Interrupt) A particular command sent to the interrupt controller to indicate that the interrupt has been handled by software and that new interrupts of the same or lower priority may now be signalled by the interrupt controller.)
 07h	reset (after failed test in virtual mode)
 08h	used by POSTsee Power-On Self-Test during protected-mode RAM(Random Access Memory)	See also DRAM, SRAM. test (return to POSTsee Power-On Self-Test)
 09h	used for INT 15/87h (block move) support
 0Ah	resume execution by jump via 40h:0067h
 0Bh	resume execution via IRET via 40h:0067h
 0Ch	resume execution via RETF via 40h:0067h
 0Dh-FFh perform power-on reset
