From 278978e953a35a2ddf27f197003b29da54e31908 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Fri, 8 Jun 2007 15:14:32 +0200 Subject: [PATCH] hpt366: disallow Ultra133 for HPT374 Eliminate UltraATA/133 support for HPT374 -- the chip isn't capable of this mode according to the manual, and doesn't even seem to tolerate 66 MHz DPLL clock...
