1.  Power off the system, but leave the AC power connected so the 5 V standby is available. 
2.  Assure that the CMOS clear jumper is in the ‘not clear’ position. 
3.  Hold down the reset button for at least 4 seconds. 
4.  While reset button is still depressed, press the on / off button. 
5.  Simultaneously release both the on / off button and reset buttons. 
Upon completion of these steps, the BMC asserts the clear CMOS signal to emulate the movement 
of the clear CMOS jumper. The BIOS clears CMOS as if the user had moved the CMOS clear 
jumper on the baseboard. CMOS is cleared only once per front panel button sequence. The BMC 
releases the CMOS clear line during the next system reset. Removing the CMOS Clear jumper 
from the baseboard can disable the Front Panel CMOS reset function. The jumper should be 
retained in case the CMOS needs to be cleared using the baseboard header. 
When the BIOS detects a reset CMOS request, CMOS defaults are loaded during the next 
POST sequence. Note that non-volatile storage for embedded devices may or may not be 
affected by the clear CMOS operation depending on the available hardware support. Refer to 
the sections specific to this platform to determine which embedded device nonvolatile storage 
areas are cleared during a clear CMOS operation.  
6.19 BIOS Updates 
There are two major changes to the current method of updating the BIOS code stored in Flash 
memory on the SE7501WV2 platform. Currently, the BIOS updates are achieved via iFLASH 
updates and by applying recovery procedures as mentioned in the Flash Update Utility section 
below. In addition, the SE7501WV2 platform also supports On-line Update / Rolling BIOS 
capability for the purpose of BIOS updates from the OS as described in the Rolling BIOS and 
On-line updates section below.  
6.19.1 
Flash Update Utility 
The Flash Memory Update utility (iFLASH) loads a fresh copy of the BIOS into flash ROM. The 
loaded code and data include the following:  
• 
On-board video BIOS, SCSI BIOS, and other option ROMs for the devices embedded on 
the system board 
• 
The Setup utility 
• 
A user-definable flash area (user binary area)  
When running iFLASH in interactive mode, the user may choose to update a particular Flash 
area. Updating a Flash area reads a file, or a series of files, from a hard or floppy disk, and 
loads it in the specified area of flash ROM. In interactive mode, iFLASH can display the header 
information of the selected files. 
Note: The iFLASH utility must be run without the presence of a 386 protected mode control 
program, such as Windows* or EMM386*. iFLASH uses the processor’s flat addressing mode to 
update the Flash component.
