I recently found a kt400 dragon ultra board and put together a system with it...It works OK but will not recognize the Athlon 3000...I'm looking for a kvx42aa6 bios upgrade...and am not having any results other than DriverGuide and biosxxx ...which I do not trust...Any Ideas?

Re: Soyo KT400 Dragon Ultra bios
The last BIOS update available for this board was kvx42aa9. I have uploaded it here: http://hitachibiotech.com/jjones/kvx42aa9.exeMachina improba! Vel mihi ede potum vel mihi redde nummos meos!Comment

Re: Soyo KT400 Dragon Ultra bios
if its an E series 3000+ thats the reason why. It would have a 200/ddr400 fsb and the kt400 chipset can't do that. I know those later via chipsets are deceptively named. The KT333 can do a 266 fsb and the KT600 can do a 400fsbCap Datasheet Depot: http://www.paullinebarger.net/DS/

Re: Soyo KT400 Dragon Ultra bios
^ I was bored and replaced the ridiculously outdated and crappy looking website I had there with that placeholder thing / dummy page
It's just a random flash animation and a viewcounter. I can't even remember where I got the flash thing from.
Nowadays I only use that webspace for hosting random files (photos and datasheets mainly), so that junk landing page will probably stay there for a while :P
@MBLeo: disposable VMs (in VMWare, MS Virtual PC 2007, Virtualbox, ..) are quite useful if you don't want to get your main system infected with questionable websites like driverguide.
That's how I got the BIOS .zip actually. Used the spyware ridden driverguide "downloader" in a Windows XP VM to get the .zip, checked it for viruses/malware, copied it out of the VM and deleted the virtual HDD file afterwards.

Re: Soyo KT400 Dragon Ultra bios
^let me add to that
If i'm not mistaken. You should be able to make a copy of the original virtual HD file, see if the current one gets infected, if it does, just delete it, rename the copied file the original file name and make a copy of that

Re: Soyo KT400 Dragon Ultra bios
Yeah.. Kinda forgot to mention that..
But even if you accidentally delete the only VHD you have, reinstalling MicroXP 0.82 (which is what I usually use ; 99MB CD ISO and about 200MB installed) takes less than 10mins from start of installation to the desktop.Comment

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
