Patch name: patch.bios-lba-head16
Author: Peter Tattam
Date: Fri Apr 5 01:03:38 EST 2002
Detailed description:
(00:58:21) PetrOS_Rules: the patch is *very* simple.
(00:59:31) PetrOS_Rules: change the line "if (hd_heads > 15) {" to "if (hd_heads > 16) {"
(01:00:03) bryce2: there are several.
(01:00:13) PetrOS_Rules: it should provide a slight performance improvement for apps which se the bios too (probably not noticable though)
(01:00:13) bryce2: well, two. should both be changed?
(01:00:47) PetrOS_Rules: yep, I think so.
(01:01:12) PetrOS_Rules: one's read/verify, the other is write.
(01:01:29) PetrOS_Rules: I'm going to take a peek at the ne2k driver.
(01:01:46) PetrOS_Rules: anyone here done any work on it?
(01:02:05) bryce2: and you think this would not cause any different behavior, only a slight performance improvement?
(01:02:52) PetrOS_Rules: yes, I think so because you don't have to call the LBA routine for the typical case where bochs has a HD image with 16 heads.
