	SMBFLASH is a BIOS upgrade utility for Super Micro Pentium / 
		 Pentium Pro boards or any 1Mb Flash BIOS.
	SM2FLASH is a BIOS upgrade utility for Super Micro Pentium II boards or
	         any 2Mb Flash BIOS.

	SMBFLASH can accept command line parameters.

	SMB2FLASH can not accept command line parameters, but can save your currenty
	BIOS image.

	You should run these programs in real mode only. 

	I. INSTRUCTIONS FOR CREATING A BIOS RECOVERY DISK 

	The mma_boot.rom and mms_boot.rom are two working BIOS images for
	emergency use.

	****** Before upgrading the BIOS, copy the BIOS files to a DOS formatted
 	****** disk and rename it to super.rom. Label this disk as "BIOS Recovery Disk" 			 Disk"

	For example: 

	Assume dive D: is your CD-ROM drive which this CD is located 		

	D:\FLSH_UTY> copy MMABOOT.rom a:super.rom (if you are using P5MMA98/P5MMA2)
        or 
	D:\FLSH_UTY> copy MMSBOOT.rom a:super.rom (if you are using P5MMS98/P5MMS2)

		
	II. INSTRUCTIONS FOR UPGRADING THE BIOS
	
	To upgrade the BIOS, make sure the following jumpers are in the right
 	position:

	 P5MMA/P5MMS/P5MMA98/P5MMA2 - J7 in 1-2 position (factory default)
	 P5MMA/P5MMS/P5MMS98/P5MMS2 - J7 in 1-2 position (factory default)
	 
	In the DOS command prompt, type smbflash <filename.rom> or just type 
	smbflash  or sm2flash ( if you are using LX or BX boards) then follow the instructions.


*****	The following instructions are for P5 motherboard only.  Your LX boards ******
*****	currently can not recovery from floppy using Ctrl-Home function.        ******

	III. RECOVERING FROM PROGRAMMING ERROR

	If the motherboard jumper J7 is in the wrong position, smbflash will show 
	the following messages at the end of the procedure:

		Flash EPROM Programming Error.
		System Will Not be usable unless Flash EPROM is replaced with
		new programmed Flash EPROM.

	Your system will not have any display on the screen after you reboot it.
  
	You should 
		1. Power off your system.
		2. Change the jumper (J7) to the proper position (1-2).
		3. Put the disk labeled "BIOS Recovery Disk" in drive A. 
		4. Press the Ctrl-Home (use the home key on the keypad 7)
		   at the same time, and while pressing the keys 
		5. Power on the system.
	
	The boot block code in the BIOS will read drive A: and reprogram
 	super.rom BIOS into itself. After this step, the system will reboot. You
 	can use this working BIOS to upgrade to a new BIOS version.



	Please refer to your manual and our web site for more detailed instructions.
