Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-questions@freebsd.org Precedence: bulk well, OK, I guess Shakespear was never really into computers. But, like Romeo, I too am facing a difficult dilemma when next I walk into a computer show or store. Because, I now have some Xmas cash burning a hole in my pocket, I want some memory, and I want it NOW. But I don't know what kind of memory I need to get. Unfortunately, since my computer is pretty much "home brew", I can't exactly call up tech support and say "hey! Do I need parity chips for a 486 computer?" People have said "check your BIOS setup program, if it has any settings that mention anything parity-related, then you probably need it." I did this, but alas, none of the configurable stuff had anythig even remotely to do with parity. Nor did any of the jumper settings on the motherboard do with this either. Nor did the manual mention anything about parity. When mentioning how to add memory, it basically said "Buy them SIMM things and stick'um in them thar little slots." What I CAN tell you is that my motherboard uses AMI WinBIOS, circa 1993. WinBIOS is the one with the cutesy BIOS setup program that has a GUI that looks like Windows. The motherboard is ISA+VLB, and supports 486 and 486-Overdrive chips (i.e. it has a socket with more pins on it than a normal 486 chip). The chipset on the motherboard is OPTi (OPTi895? can't be sure until next I reboot). I have 2 4MB SIMM sticks in there now, for a total of 8 MB. I remember when I bought them that they EACH ran slightly less than $200 (around $198 or something) including CA sales tax (7.75%). (this was last year) Neither the receipt nor the memory chips themselves say whether they're parity or not, and the store doesn't have any idea either. My guess is that my system can take either parity or non-parity, since most of the "clones" are pretty non-partial about it, and some don't even check for parity errors. I apologize for asking this here, I quite simply had nowhere else to turn. If you take offense, feel free to flame me in private. Thanks for your help, and sorry I can't be a little more specific.
