Oh dear. This is very not good. Without knowing machine level programing as well as I should, is it possible to create a patch for the, in the Linux kernel for example? Will there be a significant performance hit?
This isn't something you can fix at the OS level, it seems to be a microcode bug. Intel recently acknowledged that they enabled the ability to update microcode on Pentium chips several years ago. That's right folks, they put a backdoor in your hardware. The good news is, it could be used to fix this bug, should Intel be so inclined.
This code does NOT affect Cyrix 6x86 (166+ specifically, but probably all of them) processors. If you run a multiuser, untrusted system, I suggest reserving some at your local computer supplier... unless there is an easy fix for this, there is going to be a run on them. I don't know if AMD's Pentium-clone chips are vulnerable.
AMD's microcode is updateable too. No clue about cyrix. ______________________________________________________________________________ George Imburgia, Network Specialist Phone: (302)739-4068 Delaware Technical & Community College Fax: (302 739-3345 Office of the President e-mail: gti () hopi dtcc edu
