i think i really stuffed it i dont have backup of original bios iam trying to connect this ch341a for a few weeks now just yesterday i managed to find my problem all this time the green board between the wire and dongle was on the wrong way. ive downloaded the BIOS_IMG_rcv file renamed rcv to bin but the programmer says its too big also tech friend had a look at it and said it was bios was security protected. ive used imsprog and flashrom from linux and from windows i have tried neoprogrammer asprogrammer and original ch341a programmer. also the main reason i had trouble connecting was the dongle was faulty and wasent working i thought i couldn't install drivers for it but yeh it turns out the dongle was faulty.
i think i need bios dump and a way to bypass security protection so i can write bios file. also yes i can connect the ch341a dongle it works now any help or advice will be appreciated thanks.

ok i started of with trying to flash bios cause i did not know the admin password and while i was trying to do that with ch341a the pc stopped booting altogether. i thought i was doing the wrong thing it turns out the ch341a was faulty and was not working i bought a second hand one and that works now. for a while i was able to boot up using the dell bios file that i would put in a usb and hold esc and control while turning on the pc but now i cannot do that either.
i used imsprog to write bios file to bios chip but verification fails maybe its got write protect and also tried flashrom it too did not work also tried using different apps on windows the bin file belongs to the little fat bios 25b128esig the other one big flat one i could not read from or write to i took motherboard out tring to get a better connection to still would not work i did insure red connected with pin 1

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow
