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: ...
