I've noticed several m/b manufacturers announcing that their m/bs for the original K6's will run K6-2s with just a BIOS u/g. I'm a bit suspicious of that, AFAIK there are some significant architecture differences between the K6 and K6-2. Shouldn't that require a new/modified chipset to support properly?. Have you'd looked at http://www.amd.com ? They have lists of m/bs that they have tested (and approved) for each of their chips. I used that to decide which m/b to buy (Gigabyte GA586-TX3). Incidentally, I did this test to see how much faster a K6-2 is as I'm debating whether to u/g to a K6-2 or wait for the K7. Guess I should wait for the K7 :-) > Greg > -- > When replying to this message, please copy the original recipients. > For more information, see http://www.lemis.com/questions.html > See complete headers for address, home page and phone numbers > finger grog@lemis.com for PGP public key -- FreeBSD - The Power To Serve http://www.freebsd.org My Webpage http://www.users.globalnet.co.uk/~markov _______________________________________________________________ Mark Ovens, CNC Apps Engineer, Radan Computational Ltd.
