From 925f368193a047e1c4709d9bfa7a7644052acbb6 Mon Sep 17 00:00:00 2001 From: Mike Smith Date: Sun, 27 Dec 1998 23:23:26 +0000 Subject: From the submitter: CPU_WT_ALLOC does not work correctly for K6-2s of model 8+ and probably K6-3s (when they appear on the market soon). In addition, print_AMD_info() incorrectly printfs write allocation's size. I've fixed them, so they now Do The Right Thing, and added a "NO_MEMORY_HOLE" option to easily allow 15-16mb range handling for us K6 and K6-2 users.
