Appendix B
The Raptor MicroATX offers the optional FLASH BIOS. When
installed, you will be able to update your BIOS without having to
replace the EPROM. The General Software embedded BIOS 2000 will
read the new BIOS file from a floppy disk when running MS-DOS,
replace the old BIOS and ask you to reboot your computer.
When updating your BIOS, make sure you have a disk with the correct
BIOS file (its size should be 4Mb (512kB)).
How to reflash the BIOS:
About the General Software Reflash utility:
Reflash is a simple utility that loads a valid Embedded BIOS image,
and uses the media driver from the BIOS within that image to reflash
the BIOS.
Be aware that this operation MUST NOT BE
INTERUPTED! A power outage may be fatal. No recovery method is
provided, since Embedded BIOS does not support a boot block
recovery structure at this time.
Running Reflash from the command line:
•
Boot from MS-DOS without loading EMM386.exe and
HIMEM.SYS.
•
Have a directory containing the following files:
o

o
o
Where "BIOS" is the BIOS revision file that you want to load in
the flash part.
•
Type reflash and hit <enter>.
•
Answer yes to the confirmation question.
•
Reboot the machine when the procedure is over.
