Mac address wrong in both cmos and flash press f1 to continue

i have your problem.but when i use asrock mac tool it said "Not supported"!.infact it not supported mac address on stick on main board!but my hope was the mac 6 digit that newer tool write.then i change my mac by mac changer from windows and then set that mac to bois and flash by asrock mac tool.every thing get ok:)

1) Son follow Anti-Static Procedures?

Ram Memory could be cr@p now if not.

To include motherboard, processor, and graphics card; IF used.

2) All power cables attached to motherboard, AND tightly?

3) AMI BIOS 2.3.1

BIOS Beep Code - 3 Beeps
Indicates Ram Memory failure.

Cracked motherboard at ram memory slots, due to too much pressure being applied to motherboard, while in computer case?

Cracked motherboard at ram memory slots due to, user inadvertently had ram memory turned around backwards; and tried to install?
(Locating Notch was not lined up with Locating Lug, in ram memory slot)

4) We all get in a hurry sometimes, and make mistakes.
(Seen those commercials? Ha!)

Is there a 'stick' of ram memory in Slot 1? (DIMM 1)
That is the ram memory slot the Processor reads first.

5) I gotta' tell ya, Fred; I think we are dealing with a Static shock issue here, or cracked motherboard.

Was working, then ram memory removed/reinstalled; and now Not working.

For additional questions please post back in a Comment.

The MAC is the unique identifier for the onboard LAN chip - if it's invalid then the chip has been fried - disable it from the BIOS and install a new PCI LAN card.

Find the highest version bios flash file 1.50 and do it from DOS from a Boot Floppy or CD

Hi everyone I have a problem with the mobo asrock p4vt8 + when the boot gives me this screen: scan devices please wait ... press <tab> key into user window! serial_ch0 master: no device serial_ch1 master: no device cmos settings wrong press f2 to run setup press f1 to load default values and continue but when I press f1 or f2 the computer freezes, I want to make it recognize the hd ide but I don't know how to do it ! thanks in advance

the coin cell battery is dead
or the hdd is dead
there are 2 cures.
1: new battery and reset bios.
2: test the hDD if bad , it must be replaced and new OS installed.

configured the BIOS settings yet? Make sure your set the RAM to run as Supports DDR400/333/266 non-ECC, un-buffered memory Max. capacity of system memory: 2GB
the RAM you installed and to match the CPU bus. And there's probably several other settings that need to be tweaked as well. For example, if you're not running RAID, disable it.
If the problems continue, you may wanna try updating the BIOS. Actually, I just had a look at the ASRock site & here's what the latest BIOS fixes: "Modify MAC address function algorithm"

press delete during boot up process enter BIOS then f1 for general help then run chkdsk/r/f which will automatically fix any corrupt files on your hard drive
hope this helps good luck

What error do you see in the bleu screen of ***** bsod?

I've no guarantee but maybe you can try this download link:

K, i hv a solution for u, first u need to download afudos utility from http://www.ami.com/support/downloadagreement.cfm?DLFile=support/downloads/amiflash.zip&InpDrvID=90. And then go to DOS mode, n type command like,
D:\...........\afudos /mxxxxxxxxxxxx
There is /m is the command n 12 times x is ur mac ID. N u can find ur MAC on some were on ur MB.
I think this will fix ur problem.
