I got a rare RAID/ATAPI PCI controller here that I need to upgrade the BIOS on but the card lacks reprogrammable ROM. Is there a service/place where somebody could desolder/remove the current ROM chip, and replace it with EPROM/EEPROM/Flash PROM/anything to match the pin outs? Is this even possible to do outside the factory for modern high-density circuit boards*? How much would such a service like this cost? Where could I buy a few ROM chips (walk-in preferred) if I wanted to attempt this myself? What else would I need? so on and so on. thanks for reading.

If the pin-outs of the new and old chip are identical, it is not too difficult -- you need a good technician 字串7
used to surface mount work.
Else you need a socket converter.
Can you tell the type and the # of pins of the ROM
and the value of the VCC? perhaps I can find a replacement. <nbucska@pcperipherals DOT com> subj: eng-tips
