Re: IDE Patches bring amazing performance gain!!!

[Andre Hedrick]

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.
