SubjectRe: IDE Patches bring amazing performance gain!!!

There is one outstanding bad report in private. This report effects the
Promise PDC20262 Ultra66 host only. I tested it w/ a 1.13 BIOS and it
worked. I suggested the individual upgrade to the lastest version from
Promise. One should note this is a 48-bit addressing exception, for old
hardware.
