I added this text about 1.5 years ago.

The bug is documented in the Dino3.1 Errata. I don't recall if that got
published. Search the mail archive for "corruption".

With a dino2.1, I'd be pretty certain your box will be affected.
My understanding was HP replaced old dino chips with 3.1 versions.
For customers, this meant a board swap.

Note that upgrading PDC (firmware) may render PCI unusable.  PDC won't
let you boot (or get to PDC prompt) the box if dino is rev 3.0 or lower
*and* a PCI card (except HP graphics) is installed. It'll halt and print
something about PCI and "contact local HP support".
