I should be hereing from an Intel engineer about the problem you are having and that Peter Dufault is also having. If there are others of you out there who have an Intel 486DX4/100 (either the ODP [DX4ODPR100] or a real DX4/100 [A80486DX4-100]) and are seeing really strange crashes like illegal/privlidged intruction fault in the kernel or misc proc's that core with signals please get the above information to me so that I can add it to the open report. There has to be a *REASON* that intel went to stepping 1 V1.1 on the chip, and they can't or won't tell me what it was :-( Though both sites are having problems with stepping 0 chips, they SX/SZ numbers are quite different. There is not a S-Spec to mask data sheet for the 486 family like there is for the Pentium so I can not easily find out if the masks are infact the same between the failing chips. Even the tech support folks could not find that out :-(. I am hoping the engineer has this information! > Don't know what's under the label: and I checked it twice, > so the possibility of mistake here is minimal. That is fine, what is under the label is probably a 2 digit number, don't worry about. Intel understands all about these white labels, as all Intel Authroized distributors put them on there. If you get a chip with out one it was probably a grey market or very large direct order OEM chip. > AGL -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Custom computers for FreeBSD
