I haven't tried the patch yet, but yes the motherboard is an (early
version I guess, as the 53c1010 is a 33MHz version, not 66MHz as 
documented in the manual) ASUS CUR-DSL: ServerWorks OSB4 chipset,
Symbios Logic 53c1010 Utra 3 SCSI two channel HA, dual Pentium III 
(up to 1GHz I believe) capable, but only one 933MHz CPU installed.
