[Pc_Support] Opteron 100 goes Socket-939 (unreg-mem), ServerWorks HT1000 to go it alone ...

[Bryan J. Smith]

To start, AMD is moving to Socket-939 for Opteron 100, which includes
use of unregistered memory (both ECC and non-ECC).  This will bring down
the cost of entry-level servers with single processor, single and dual-
core Opteron 100 series.

It also seems that entry-level server mainboards with PCI-X might be
dropping under $200 soon.  The Broadcom/ServerWorks HT1000 might start
making a sole appearance on new Socket-939 mainboards for Opteron 100.
This means you'll have a single PCI-X channel, possibly one (1) 133MHz
slot, two (2) 100MHz slots, or maybe two (2) 66MHz slots plus on-board
peripherals (like GbE).

To date I've only seen the HT1000 implemented alongside the HT2000.  But
the HT1000 is clearly capable of being on its own with LPC/PCI support.
This is unlike the HT2000, which must rely on the HT1000 for LPC/PCI.
Although the HT2000 does add PCIe, a 2nd PCI-X channel and on-chipset
dual-GbE, the HT2000+HT1000 combination is >$500 in a mainboard.  I'm
hopeful the HT1000 on its own will be <$200.
