Hi guys,
I've been trying to recovery a Compaq Evo N150 that was shutted down during a bios update and now it doesn't POST. I have a ROM file from the update utility, but don't have a chip programmer like the tl866. I tried the bios hot swap method on various motherboards, using uniflash on some mobos both the chipset and the bios chip is detected properly, but when I hit flash including bootblock, I only get red squares on the preview, and fails the checksum. Using various bios update utilities (awdflash, amiflasher, phlash16), it always fails either the checksum or it detects that the bios of the mobo is different from the one I want to flash, and refuses to do it. Also, I don't have any boards that also uses the phoenix bios, only award or AMI.
The eeprom of the compaq is a 28sf040, 5v 512K. I've been trying the hot swap method on a pcchips M925 (AMI), pcchips M789CG (AMI), Mitac 5114vu (Award 6.00). All of them have via chipsets. I have a few Intel ones but they use the hub architecture (i815, i845), and also 3.6v eeproms, so I assume those could either kill the eeprom/mobo or won't work.
I also know some BIOS have recovery options, like the bootblock recovery from award, but I don't know if this BIOS has that option and how to trigger it.
Is there any other way of flashing back the BIOS file, or something I am doing wrong?

Thanks in advance!
