There is something wrong with installation of drivers in 1.0f. there are many lines missing in TXTSETUP.SIF. Here are some examples: e1000nt5.sys = 1,,,,,,,,3,3,,1,4 e1000nt5.sys = 2004,,,,,,,2004,0,0 missing in 1.0f iastor.sys = 1,,,,,,4_,4,1,,,1,4 iastor.sys = 1992,,,,,,,1992,0,0 missing in 1.0f nv4_disp.dll = 100,,,,,,,,3,3 nv4_disp.dll = 2006,,,,,,,2006,0,0 missing in 1.0f nv4_disp.inf = 100,,,,,,,20,0,0 nv4_disp.inf = 2006,,,,,,,2006,0,0 missing in 1.0f If I manually change the TXTSETUP.SIF it works even with Intel RAID. rc8 works OK
