My SC450NX Xeon box (from www.sagelec.com) is now up and running
3.0-RELEASE with 2 cpus and 1GB of DRAM. I bought an Adaptec 2940
to get round the ncr driver problem with the onboard Symbios 53C896.
The onboard video (Cirrus Logic CL-GD5480) also seems to work ok
with XFree86 (choosing GD5464 as the card type in XF86Setup).
Everything runs fine so far, and the 400MHz Xeon blows away our
300MHz UltraSPARC-2 boxes (did a big gcc compile in 440 sec vs 761 sec).
With 2GB of DRAM it still crashes - here are the details:
...
BIOS basemem (633K) != RTC basemem (640K), setting to BIOS value
BIOS extmem (15360K) != RTC extmem (65535K)
