arse, well that explains then why it didn't work =) oh well, it suffice as a name server which is all I had it doing anyway. I wish I could remember how old this thing is. the BIOS date is 1992 or 1994ish. my main reason for wanting to force it into I586 was wanting it to work in 32bit mode. if I remember correctly 486's were only 16 bit. according to AMD's website this thing is supposed to work in 8, 16, and 32 bit. I remember 486DX4's I had one back in the day but I didn't remember those working at 32bit. I had never been to AMD's website before because I've never bought an AMD (this laptop was a gift when I was much younger) mainly because it wasn't until the last year or so that AMD churned out multiprocessor capable equipment. I found this white paper though. which is what I'm referencing. http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_doc s/19751.pdf unfortunately, I'm not a chip guy, I'm a router engineer so roughly 80% of this document is nonsense to me. if I have my kernel configured as I486 will I still have 32 bit support in the OS? I guess the question is more or less moot since it won't boot any other way =) Thanks for the response =) -----Original Message----- From: Toomas Aas [mailto:toomas.aas@raad.tartu.ee] Sent: Friday, March 08, 2002 1:05 AM To: Jesse Geddis; freebsd-questions@freebsd.org Subject: Re: CPU type Hi Jesse!

AMD 5x86 *is* a 486 class CPU. You can think of it as 486dx4. Your CPU works at 133 MHz (33 MHz FSB x 4). The "P75" is a marketing blurb which wants to tell you that this CPU is approximately as fast as Pentium 75. -- Toomas Aas | toomas.aas@raad.tartu.ee | http://www.raad.tartu.ee/~toomas/ * If you don't think women are explosive, drop one. _________________________________________________________ Do You Yahoo!?
