Yup Yup Yup....

That's the *exact* same thing I'm dealing with now.

Your BIOS chips are too old.  

It's probably not your controller card, since I replaced mine with
*no* effect.

Pick up a copy of Computer Shopper at your local Mag store.  Plenty of
places deal in AMI BIOS upgrades.  Expect to pay $40 to $60 for it.

At least you *know* what BIOS chips to get.  Mine are Access Methods,
Inc, whoever *they* are ;-}

  This is a followup to the article I posted June 3rd regarding upgrading
the ROM BIOS chips in a 1986 PC/AT.

  What it all boiled down to was this.  The motherboard was made by Everex
and used AMI BIOS chips that had been made specifically for that board.
This made it impossible to use a "generic" AMI BIOS upgrade and instead I
had to order an upgrade set directly from Everex.

  Interestingly enough, the cost of the upgrade and UPS Blue shipping was
only $44.00(US).  This is much lower than the 69 to 80 dollar quotes I was
getting from other companies.  The Everex people were very nice to deal
with; completely professional and VERY courteous.
