1. Unplug Your HD, Floppy, and CD Drive (includes DVD,CDR(W)), then boot it
up, make sure the fan is running on the heatsink, if so there's power on the
motherboard. How see if you get video.
2. If not, Try the Video card on another machine to make sure it works, if
it works I would suspect the CPU.
3. Take everything off the motherboard, execpt for the video card. Now
boot it up leave it on for just about 20 secs. Shut it down, and carefully,
but quickly take off the heat sink. Take the chip out, the chip should be
warm on both sides.
4. If the CPU is warm that's a good sign, if not it's a bad sign. We need
to confirm if it's the Motherbaord BIOS or not....If you have a friend that
has a similar AMD chip (that's compatible with your board of course) then
try it on your motherboard, or take it to a computer shop to see if one of
their CPU's will work. IF it boots up then you'll know if it's the
chip.....If it doesn't then we know that it's the motherboard.
5. Now assuming you've tested the board with another chip and it does not
boot, it could be the entire board itself is dead or the BIO's memory wasn't
properly flashed or the BIO's chip is entirely bad. Most newer BIOS's have
what is known as a boot-block that is hard coded on to the BIOS
chip....Here's what I have on it:
Boot-block BIOS
Modern motherboards have a boot-block BIOS. This is small area of the BIOS
that doesn't get overwritten when you flash a BIOS. The boot-block BIOS only
has support for the floppy drive. If you have a PCI video card you won't see
anything on the screen because the boot-block BIOS only supports an ISA
videocard.
Award: The boot-block BIOS will execute an AUTOEXEC.BAT file on a bootable
diskette. Copy an Award flasher & the correct BIOS *.bin file on the floppy
and execute it automaticly by putting awdflash *.bin in the AUTOEXEC.BAT
file.
AMI: The AMI boot-block BIOS will look for a AMIBOOT.ROM file on a diskette.
Copy and rename the correct BIOS file on the floppy and power up the PC. The
floppy doesn't need to be bootable. You will see the PC read the floppy,
after about 4 minutes you will hear 4 beeps, this means the transfer is
done. Reboot the PC and modify the CMOS for your configuration.

Subject: [PCBUILD] No BIOS / Boot...
Hope somebody can help... this is driving me crazy!
Purchased an FIC AZ11 m/board and Duron 800 chip new as the foundation of a
new system build. Also purchased a new case / power supply, RAM chip, and
video card. Other parts <floppy, CD ROM, hard drive> were working spares I
had laying around.
Assembled system <I have assembled many Pentium systems prior to this> and
was ready to go. Powered up fine <all accessories, fans, h/drive, CDROM>
but it appears no signal is being sent to the monitor. So, I re-check all
the connections and try again. Still, nothing but a black screen <monitor
is fine>.
I re-checked all the jumpers, re-installed the CPU, tried booting without
various components <h/drive, floppy, CD>, tried different video cards, RAM,
hard drives, etc., but there is still no signal being sent. To make it more
difficult to diagnose this m/board apparently uses some "spoken word"
program to diagnose BIOS errors which requires an add-on card which I don't
care to use or buy.
I don't have another AMD based board to test the chip, either. Only hint: if
I hit the reset button I at least get a temporary flash or "line" in the
monitor for a brief second..... anybody have any ideas before I send this
thing back?
Any help would be MUCH appreciated......
