Thanks for the advice. I'll definitely give it a try tonight. Yes I did flash the bios from the A: drive since I was unable to use the Update utility that came on the Asus Installation CD (damn rebooting). I REALLY hope the sirens stop because it's such a downer when I hear it go off. Thanks again and I'll fill you in on how it goes.

If that doesn't work, try reseating your CPU... just take it out and put it back.

Sounds crazy, but it's worked for others to get rid of the Damm sirens.

I've actually tried that already too. I reseated the CPU and tried the RAM in both slots (1 stick Corsair 512MB266) but I still get the sirens. I also applied more heatsink gel since I read somewhere earlier that the CPU may think it's overheating but nothing changes.

Ok, so I did as you guys advised and took out the CMOS batter, unplugged it from the wall, and even unplugged the power supply connection and I am still getting the sirens. I also tried holding the Delete button when starting up to see if I could get into the BIOS, but the sirens won't even let me get to that point of the boot process!! I believe something have been messed up during the BIOS update (since that's when the sirens first appeared). The first mobo that I put together had this same problem too, but I reseated the cpu and it went away (for awhile). Then it came back and I decided to RMA it. The current mobo that I have is the replacement and now it's doing the exact same thing!!! I'm dyin' to figure out what's wrong with it. Can somebody please help me?

Logically, you could rule out the motherboard as the problem since you've replaced it already and still have the same problem. I'm assuming you didn't mess with the bios on the first board. If you paid attention when you updated the bios, it would have given you an error message if something went wrong. I took out my two sticks of memory...256K Kingston modules.... and rebooted. All I get is a long tone...then pause....then long tone pause etc. I don't know if this is the siren sound you're talking about or not. When you take out all your memory and try to reboot, does the tone change from what it is with the memory in? Mine booted up with memory in either slot.

I got some problems when building my computer.
I put hard disk on IDE primary master. Ok
I put CD-rom on IDE secondary master. Ok
I put floppy drive. Ok

There is no SO installed, cause I just bought the pieces

Now I'm trying to boot from the floppy. (I set the bios to primary boot drive = floppy)
If there is no floppy inserted, it shows "System boot failure. Insert boot disk and press enter", or something like. That's normal.
But if I turn on my computer WITH floppy inserted, it shows error "floppy disk(s) fail (40)"

Anybody knows whats wrong?

>> BOOT floppy problem
You need a BOOTABLE floppy inserted, if you plan to 'boot' from the floppy drive.
You can create one in practcally any version of Windows, if you don't already have one, and you SHOULD!

The floppy is already a bootable win98 formatted disk

A common mistake is plugging the ribbon cable into the floppy drive backwards. The wire marked with red goes toward the center of the drive. .

Sure, I have plugged the cable just like you told so..

>> HELP!!! K7s8x crash with Nvidia tnt2
i recently upgraded my syetem the specs are
ddr ram 256 mb
nvidia tnt2 64 model 32mb
maxtor 40gb hard drive 5200rpm
amd athlon 2500+

the system runs slower than when it was
duron 850mhz
nvidia tnt2 64 model 32mb
maxtor 40gb hard drive 5200rpm , why

plus the system crashes (freezes) after a few minutes of starting is it the processr or the vga card?
plus the card seems not to be able to draw the screen properly (but this is the same card on my old 850mhz system),

the computer also says it cant find the drivers to the virtual clone drive? what is the virtual clone drive?

what can i do to stop the crashes and speed up the system (stopping the crashes is my priority)?

thanks for your help in advance

sean moses:

If you go to the ASUS site at
it doesn't list the 2500+ as being supported on the A7N266-VM. This could be your problem.
Make sure you are using the correct BIOS for the processor you have also. You might be able to use the 2500+ processor at some slower speed...maybe 2200...I'm not sure. I'm using a 1700 Also, the FSB jumper is probably set at 100 for the 850 Duron and should be changed to 133 for the 2500+.

Read the first line in sean's post above... He is asking about a TOTALLY DIFFERENT mobo to our A7N266-VM.

And BTW, our mobos WILL support the 2500+, but unless you do the 'solder mod', it'll run underclocked.
I apparently haven't even tried my 2500+ in my A7N266-VM yet, but I will soon.

With my 1700+ DLT3C JIUHB, and the 'solder mod', here's what it'll do...

>> Re: HELP!!! ASUS A7N266-VM
You're right...I missed the part about it being a different motherboard. Sorry about that. Without doing a bunch of research on his board, I'd guess his 2500+ is running slow because of improper CPU settings in the BIOS...having updated from a Duron 850. He may need a BIOS update.

Also...I can't seem to find an Athlon 2500+ with a FSB of 266Mhz....are they all 333Mhz Bartons?

Hey! No prob, you were just trying to help after all!

You CAN change the boot speed of any of these CPUs by cutting / joining a L12 bridge.

Thanks for the info. Guess I can stop looking for a 2500+ with 266 FSB.

for sean moses:
You need to make sure you have the FSB jumper set to 333 on your motherboard. This is different than the setting for the 850 Duron.

i have the se version of the above mobo, with an xp2000, 256 generic DDR, and a hercules gforce2 Ti 64DDR and have almost identical problems with mine.
Mine however was a new mobo,ram 'n' chip for an old p3 system. i also had psu trouble and all at the same time.
the oe: 0167 type error that comes on all the time has a software fix out there (sorry i dont know more acurate data, one of those 5 in the morning fixes :( )

i think it must be an inttermited problem but they are holding back a recall, because i have seen far too many of us in my quest to fix this bloody thing.

2 more thoughts...

Does anyone have one of these boards and can successfully play a huge battle in SHOGUN TOTAL WAR

How many of you IDE slots full like me, or only use a few slots (asuming 1 physical is 2 virtual)?

we need more knowledge of success stories and their tech breakdows...i have a ti graphics like above guy, how many more are using nvidia on this nvidia board is that the prob?
still too many variables.
please help us anyone that can. i am unfortunatly not in a position to afford to just throw money at it till i find a cure, but i bet one of us must know a friendly rich

it seems my voltage is a little bit higher about 12.3V (it is high to me)
