[-- Attachment #1 --] Hello all: I've been using FreeBSD successfully for several years now to run my website (http://www.vtec.net) I'm in the process of reconfiguring/upgrading a server and decided to go with 4.2. I'm having a problem with my system when I'm running the 4 DIMM slots fully populated to 1GB of SDRAM. I searched the mailing list archives and newsgroups and several websites to no avail. Initially, the configuration of the machine was: Tyan Thunder 100 (S1836) - 440GX chipset Dual Pentium III/550 Processors 512MB PC133 SDRAM (Micron) Onboard fxp (Intel 82558) 100Mbit NIC Onboard Adaptec AIC-7895 UltraWide SCSI 7200 RPM 20.0 GB WD IDE drive for the system (to be added) 4 10kRPM 18.2GB SCSI drives (planning to possibly use Vinum) With this configuration, I successfully installed 4.2-release from CD-ROM. I reconfigured the kernel to support only my devices and the dual processors. I successfully added a few ports and then realized they were slightly outdated so I removed them. I then added two more 256MB DIMMs (identical to the other two) to bring the RAM total to 1GB. The system booted fine at first but then during the sup process for updating the ports collection it began behaving strangely. I have tried tweaking some BIOS settings (DRAM Refresh Rate, for one) with some degree of success but the system is still behaving erratically. Has anybody else observed this sort of problem? thanks, Jeff [-- Attachment #2 --] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=iso-8859-1"> <META content="MSHTML 5.50.4134.600" name=GENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=#ffffff> <DIV><FONT face=Arial size=2>Hello all:</FONT></DIV> <DIV><FONT face=Arial size=2>I've been using FreeBSD successfully for several years now to run my website (<A href="http://www.vtec.net">http://www.vtec.net</A>)</FONT></DIV>; <DIV><FONT face=Arial size=2>I'm in the process of reconfiguring/upgrading a server and decided to go with 4.2.
