Tried hotflash which was a success but motherboard still doesn't post 🙁

Save vintage / retro computers from ending up in the bin. Keep them in working condition. It's a great history !

It's in PCI slot, no codes, all leds on apart from 3.3 Volts, irdy, frame, reset. No beeps
In ISA as you can see.
Dead ???? or there is still something I can do or try ?

When using the ISA slot you have it plugged in backward

Eeeeeeeeeee I thought it was the right way 🙄
So that rear thing means rear of the computer and not the rear of the isa slot which is the opposite side .....

Only one part get hotter to around 40-50 Celsius is Winbond W83768F but this is the I/O controller

its not, its a buffer for serial ports, if it gets hot it might be blown, wouldnt be the first time

Processor, ram, video card are fine, power supply too. All tested on other mobo and no issues.

check for 5V 12V rail resistance on the motherboard

what I can see is a POST card with a "REAR ->" printed on it plugger wrong way
now its too late, you probably fried either post card or chipset
