After battling for days with a Dolch 65 that developed
the two-tone

gone bad. The BIOS happens to be an Award BIOS, says "Award 1998 PCI/PNP
686" on the chip. It's a square chip with pins on the side.

So I thought I might just ask. Anyone has a dead Dolch 65 motherboard from
which I could steal a BIOS chip. The board is actually an Advantech CI6BM-B1
industrial single board computer.
Or alternately, can someone identify what kind of ROM or EEPROM that likely
is, and provide advice on how to read the data from a good chip (I have
another good chip in another Dolch, that's how I found out what my problem
was), and program a similar chip.

Surely you must have a PLCC capable device programmer hidden away
somewhere in your not so secret basement lab. And if you don't have
one, why haven't you built one up from an HP-85 and some GPIO
adapters?
I also have a PAC 65. I'll have to open it up and take a look. Wish
there weren't so many screws involved. Whatever that 32-pin PLCC part
is I should be able to read its contents with my BP Microsystems
BP-1610 device programmer. I could program a new one if I had some of
the same part on hand.
