From: hyphen@chobby.demon.co.uk (Tony Stiles) Subject: Cyrix cacheing - helpful info? Date: 13 Jun 1993 14:16:39 GMT
Greetings Cyrix Linuxers and Coherenters,
I hope this is a useful bit of info.
Anyone who uses a Cyrix chip will be aware that they need to run a DOS
program DO_CACHE or some-such in order to kick in the INTERNAL cache memory,
and so we all have a call to this program in our AUTOEXEC.BAT.
By default, I would always hard boot my machine into Linux - since that
is what I wanted to use. Sometimes I would boot into DOS since I wanted
to use a DOS app and then I would soft boot into Linux with Ctrl-Alt-Del.
When running my (huge) Linux app, it would usually run at a so-so speed
and sometimes it would run like CLAPPERS! I couldn't figure out why....
Anyway, it looks like I have now found out why - whatever the DO_CACHE
program does, it doesn't seem to be lost during a soft boot :) - and it
really does make a difference worth worrying about!#
[[ So if you use Cyrix, always boot DOS once to install DO_CACHE bits ]]
Does anyone know how I can find out the specs on the Cyrix Cache loaders?
It might be useful to produce equivalences under Linux.
Tony
