You solder the wrong SPI BIOS chip on the wrong board...... then press go..

Re: what happens say if....
As long as its the same chip, probably nothing. it shouldn't go up in smoke unless you put it in backward or something....but if the POST config on the eprom doesn't match the motherboard, it simply just won't POST.<--- Badcaps.net Founder

Re: what happens say if....
SPI BIOS chips are similar in size to SOIC-8. I'd rather solder a SOIC-8 than any other chip. Light years between leads so alignment is easy and solder bridges are rare. They are almost as easy as inserting and removing a DIP from a socket.Comment

that's why my flasher board has a ZIF like socket for them

Re: what happens say if....
If they are SPI they probably support in-circuit programming.
My MSI 790GX-G65 even provides an ICSP header but you may be able to get away with just tacking or clipping some wires to the appropriate pins...

So I'm trying to get into micro soldering, repairing tech etc.
I bought a load of equipment, The YIHUA 853D 2-in-1 station, 1080p Microscope with 10", I do not have low-melt or leaded solder yet, I have tried flux 'paste' in a tube, very liquidy seems to blow away, I've tried flux paste in a tub, still no luck.
I have tried 3 different boards, a router, an Xbox One Fat and now a Pi400, none show ANY signs of melting solder, components don't budge.
My method:
Preheat board with hot air (Small nozzle as it's directed, as I'm told) at 250c
Apply flux to component... -
Hi,
I was given a laptop with a BIOS locked by a password. I read that one way to unlock it is to read the EEPROM contents, patch them, and write them back. I was using the typical CH341A programmer and clip to do this, but because the clip is so loose, after patching the dump I accidentally placed the clip on the wrong EEPROM and now the laptop won’t boot.
Can I do something to fix it? I’ve attached photos.

Hi,
Anybody has experience repair PSU burned out due to connect to EVGA molex/sata cables. I know the cable is not compatible (i got them mixed up), but I though i can connect it and use a PSU tested to find out which is the wrong sata/molex cables. As soo as I pluged in the powered molex cable to the PSU tester, the power supply short out, and will not turn on anymore. After the incident, the PSUs (both HX1200 and C850) try to power on and shut itself off immediately. The ATX PSU tester survice the short circult, still working perfectly. Anybody know if it's an easy fix or know which parts... -
Hello everyone.
I have come here with a rather specific question. I was given a Dell Latitude 7420 laptop with a busted screen, and wanted to see if I could refurbish it into my daily driver. I wanted to experiment and see if a 2-in-1 display would work as the chassis of the laptop and 2-in-1 7420 looked identical. I threw in the display and my hypothesis was correct, however, I was greeted with a locked BIOS and since I didn't know the password, I figured I'd try to unlock it somehow. I bought one of those POGO pin probe things for my CH341A programmer so I could read and make... -
Hi everyone,
I hope someone can help me.
I have an Asus ROG Strix Scar 18 (G814JZ) laptop with a Winbond 25Q16JWNIG chip on the motherboard.
Unfortunately, I flashed the wrong file (BIOS/EC/other region – I'm honestly not sure anymore), and now the laptop is completely dead: no display, no fan spin, no reaction at all.
I have a CH341A programmer and I'm able to read and write to the chip. However, I'm not sure which software is best (AsProgrammer, NeoProgrammer, etc.) or if there's anything specific I should watch out for.
A valid BIOS/EC backup...
