Here is a utility that Cyrix DLC users can use to activate their
1kB internal cache if their motherboard BIOS does not do it for them.
Note that it is a stand-alone program and hence no kernel patching
is required.
I have sat on this for the last six months because Linux
will not allow access to CPU reg. "cr0" even with uid=0 and iopl(3),
which means that the program is limited in functionality as compared to
it's DOS counterpart. However it is still useful even in this
form, so I am setting it loose. (BTW, the fix to iopl() is probably
a one-liner if you have an i386 Programmers Reference handy...)
Pleas, PLEASE read the "README.linux" and the "README" files included
in the package. There is a man page too, so RTFM, especially the
"BUGS" section. :-)
Uploaded to incoming on sunsite, to be moved as per lsm below.
