Hello all:

I've been using FreeBSD successfully = for several=20 years now to run my website (http://www.vtec.net)

I'm in the process of=20 reconfiguring/upgrading a server and decided to go with 4.2. = I'm=20 having a problem with my system when I'm running the 4 DIMM slots fully=20 populated to 1GB of SDRAM. I searched the mailing list archives = and=20 newsgroups and several websites to no avail.

Initially, the configuration of the = machine=20 was:

Tyan Thunder 100 (S1836) - 440GX=20 chipset

Dual Pentium III/550 = Processors

512MB PC133 SDRAM (Micron)

Onboard fxp (Intel 82558) 100Mbit = NIC

Onboard Adaptec AIC-7895 UltraWide=20 SCSI

7200 RPM 20.0 GB WD IDE drive for the=20 system

(to be added) 4 10kRPM 18.2GB SCSI = drives (planning=20 to possibly use Vinum)

With this configuration, I successfully = installed=20 4.2-release from CD-ROM.

I reconfigured the kernel to support = only my=20 devices and the dual processors.

I successfully added a few ports and = then realized=20 they were slightly outdated so I removed them.

I then added two more 256MB DIMMs = (identical=20 to the other two) to bring the RAM total to 1GB.

The system booted fine at = first but then=20 during the sup process for updating the ports collection it began = behaving=20 strangely.

I have tried tweaking some BIOS = settings (DRAM=20 Refresh Rate, for one) with some degree of success but the = system is=20 still behaving erratically. Has anybody else observed this sort of = problem?

thanks,
Jeff
