I have spent some time digging around the internet archive and can't seem to find anything more than a manual for this motherboard.

It is an Asus WMT-LX rev 1.04 Socket 423. Looks like it came from some Sony desktop maybe a Vaio PCV-RX370DX based on this link I found with my exact issue.

Mine also came with a 1.3GHz cpu which works great, but I got a 1.9GHz chip and no POST after the swap It currently has BIOS 1003

Might need a fresh set of eye if someone can come up with some BIOS leads on this?

Thanks so much guys.

Well things went south, imagine that...

After reading this page

http://vaiochan.at-ninja.jp/html/rx62cpu.htm

it seemed this board was actually a re branded P4T-M from ASUS. Asus even still had the support page up for this board amazingly. I downloaded the manual, and when everything did infact match perfectly component wise I promptly downloaded the BIOS and the flasher, booted up with a 6.22 bootdisk and flashed the board. Everything seemed great, but after the reboot, no POST. Maybe I should have used the /BOOT switch cause it said it did not update boot block or ESCD.

So I guess i need a programmer. Suppose I have been lucky enough not to need one til now. I really want to use this board so I need some programmer recommendations that will clip on the chip so it can program it. Luckily I did save the BIOS before programming so hopefully we can get back to square one.

Thanks for any programmer suggestions.

Because I like to rub the salt in the wounds, I tried to boot the machine one last time before heading to restless sleep. To my amazement it posted. I couldn't believe it. After reviewing the CMOS settings and putting a new battery in, I shut it down and swapped out the CPU for the 1.9GHz, and it indeed POSTS now. Don't know if there are going to be any issues down the road with this alternative BIOS or not, but it looks like it is working now.

Very strange cause I pulled power/battery/etc before with no luck. Glad it decided to spring back to life.

Well for S&G I went ahead and put the jumper on clear CMOS to see if that is what caused the original issues, and it seems to indeed cause no POST again. So maybe a default setting in the CMOS is what is causing the black screen. So it looks like as long as the CMOS battery stays up then it is good as I removed power and rebooted about 12 times before trying the clear CMOS experiment. Leaving the board unplugged and CMOS battery removed now to see if I can get the board to come back.

Well system came back to life, so I thought what the heck, and reflashed it again, this time with the /BOOT option to get the boot block. Well looks like that killed it, as I have let it sit and now it won't POST again whatsoever. So the programmer recommendations is back on the table, 🤣..

Hi, while I don't think it's the cheapest option, I use a chinese TOP3000 EPROM programmer and so far it was worked well for anything I have needed. In your case you would also need an adapter, because the programmer only accepts DIP chips, not those with legs on all four sides, whatever they are called. Good luck with the board revival.
