After battling for days with a Dolch 65 that developed the two-tone
beep-of-death on boot, I finally found that it's just my BIOS ROM that has
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.

It's probably something like a 28F010 / 040 flash chip, or something like that.
Look at which address lines are connected and you can figure out the size of the thing.
Most hobby programmers like Willem etc. will program those, reading shouldn't be a
problem at all the foot print of these parts are all the same.

I just checked and my memory was not correct. I have a PAC 63 and a
PAC 64, but I'm not sure what the model is of the one I thought was a
PAC 65. That one doesn't have a model sticker on it. I didn't open it
up to take a look. From the BIOS POST screen it has an i440FX chipset
PII 266MHz CPU board with an AMI BIOS with a copyright of 1996. So
that's not the same as your copyright 1998 Award BIOS PAC 65.
The other ones I have are newer P3 FlexPAC boxes.

Glen,
I think I wasn't thinking straight late last night when I finally found the chip was
bad... I usually don't work on stuff that "new", so I was unfamiliar with
the PLCC 32 format and have nothing to program it. I bet the reference of what chip it is
hides just under the label! Assuming this is a run-off-the-mill EPROM chip, one should
indeed be able to copy it with a semi-recent EPROM programmer (i.e., not mine...). Now, if
it's one of these fancy Intel "Firmware Hubs" with copy protection, I am
probably hosed. But I doubt it since there is an appropriately archaic CMOS settings chip
next to it, so hopefully it is just a traditional ROM in a fancy package.
BTW to take a look at that bios, you have to take the plastic back off, then the metal
cage back off, then the strip with the serial connectors off, then the power supply off.
It's 15 minutes work and 16 screws...
In Dolch we trust.

And lifting the sticker reveals the BIOS chip is just a W29C020P-12, a
regular 256k x 8 Flash memory, 5V chip. Duh. Mystery solved. Of course way
newer and with many more address lines than my DataIO 29B can read and
program. Time has come to buy a small, modern, cheap, infinitely capable
Chinesium EEPROM programmer. Read: the kind of practical, affordable,
sensical and useful equipment I usually steer away from. Ebay here I come.
Or make a programmer with an Arduino, since it's 5V.
What about the TL866 that Dave at EEVBlog likes? Does it have a PLCC
adapter? Anyone has another recommendation?

Actually the TL866A universal programmer comes with a PLCC-32 adapter included for about
$50, including slo-mo shipment from the other end of the world and the extra tariff for
the Chinese steel that must be hiding in it. And probably sharing a ride in the same boat,
I should get some W29C020P?s. Which might chooch or not, on account of them containing
either real or fake chips. In the latter case I will only will have lost a few American
rupees and I can leave a blistering negative comment to further sink the already
alarmingly low rating of my seller before he switches identity. So odds are in my favor.
All electro-magically transacted on ePay based on fuzzy pictures for the gullible and
funny money from PayBuddy. Oh the miracles of your new world economy.
