Thunder HEsl (S2567) FAQ Updated 07/07/03
 

1. What precaution should I take when flashing BIOS?
   
   If your BIOS chip has part number SST 28SF040A, DO NOT flash the chip with BIOS versions below V.1.03 ; otherwise, the older BIOS version would render your system inoperable.  See illustration.
    
2. After I flashed the BIOS chip, why is my system not working?
   
   If your BIOS chip has part number SST 28SF040A, and you flashed it with older versions of BIOS (below V.1.03), the chip will stop working.  The chip cannot be flashed again.  You will have to obtain a new BIOS chip.  The recommended chip vendor is BIOSWorld.
    
3. I'm using console redirect on this board with Redhat Linux.  After upgrading to BIOS 1.04 or higher, I can no longer get into the CMOS setup like I could with BIOS 1.03 and below?
   
   Use the F4 key to get into the CMOS setup of BIOS's V.1.04 and up, and the DEL key for BIOS V.1.03 and below.
    
4. Does my TYAN board support Linux operating systems?
   
   During pre-release testing, our compatibility engineers run our products through a battery of tests, including operating system installations. We currently perform basic installations of many operating systems including Red Hat Linux and SuSE Linux. Although we do perform installations of these O/S's, we do not guarantee complete compatibility, primarily due to the open nature of the source code. As we do with all of our products, we strongly encourage you to purchase our products through reputable dealers that provide adequate return and service policies. At present, we do not provide technical support for Linux-based inquiries.
    
5. Why isn't my system stable?
   Instability can be traced to many different causes.  The one cause most associated with instability is heat.  9 times out of 10 the heat sink is not installed properly on the cpu itself.  The heat sink must be installed perfectly flat upon the cpu with the proper amount of heat sink compound between the cpu and the heat sink.  There simply can be no daylight between the heat sink and the cpu.  The other issue is that the heat sink and fan simply are not rated high enough to disperse the heat from the cpu in a timely fashion.
