	ROM and give control.
Award	(2C)Enable slots C;Initialize slot C.Detect & initialize serial ports.
Compaq	(2C)Boot.
Dell	(2C)[Beep]=3-4-1 screen initialization in-progress or failure.
Phoenix	(2C)RAM failure on address xxxx.If the BIOS detects error 2C,2E,or 30(base 512K
	RAM error),it displays and additional word-bitmap(xxxx)indication the address line
	or bits that failed. For example, "2C 0002"means address line 1 (bit one set) has
	failed. "2E 1020 means data bits 12 and 5 (bits 12 and 5 set) have failed in the
	lower 16 bits. Note that error 30 cannot occur on 386SX systems because they have
	a 16 rather than 32-bit bus. The BIOS also sends the bitmap to the port-80 LED display. It first
	display the check point code, followed by a delay, the high-order
	byte, another delay, and then the low-order byte of the error. It repeats this sequence
	continuously. Test 512 base address lines.(Beep)= 1-3-4-1 Activate interleave(if
	possible).[Beep]3-4-1 screen initialization in-progress or failure.
	Error Code - 2D

	video ROM returns control.
Award	(2D)Enable slots D; Initialize slot D. Detect & initialize parallel ports. Test timer 2.
