Hi,
Some more LBACACHE vs. SMARTDRV tests, I think these are the last ones for
now.
Tests for 386 SX/20, 31 MB FAT16 partition on SCSI hard drive
CONFIG.SYS and AUTOEXEC.BAT remain the same except for the changes in
caching method.
No disk cache, 3:39
LBACACHE 2 MB, 2:54
SMARTDRV 2 MB, 2:34
Hi, forwarding a comment by Lawrence, maybe interesting???
Well, it happened in an older version of the GRDB
debugger. It has since been fixed.
By the way, I don't have time to investigate this now,
but while I have your attention, I noticed that when
the BIOS allocates an XBDA at

Hi Arkady!

How this relates to DOS?
MS DOS basically had no 386 stuff at all (except EMM386). In FreeDOS,
however, people run 386 aware programs more often. Those leave non-zero
values in 32 bit registers when they exit, and the next program which you

Hi Aitor, Alain,
please ask Lawrence first if the MS DOS kernel clears the 32 bit
registers. I bet that it does NOT.
This is not related to is the program which breaks unimportant.

MS-DOS is a 16-bit OS.
ASM io.sys and msdos.sys are 16-bit, emm386.exe is 32-bit.
But emm386 is not part of kernel.
Ok, let suggest, some demo-maker makes demo, which will depends from

I test it. APMOFF, APMBIOS, INFO, STATS and STANDBY doesn't work (no
APM). About flushing cache in standby don't know. SUSPEND stops my hardisk.
Hi, I think idleness percentage is easier to understand for users than
time of using HLT versus total FDAPM loaded time
in general :-). Displaying TOTAL time is a bit complicated in NASM but would
be a nice extra (uptime display).
Only with the resident module you have an idleness percentage -
