ADDD replied to Fernando 1's topic in nLiteFernando 1, thank you for this great thread. I regrettedly confirm that v9.99.09 (performance pack) XP x86 drivers do not work with system partition residing on NF4 RAID0. I beleive GTS driver has some incompatibilities with MS's way to check devices and load drivers at startup. Perhaps the issue can be resolved by altering ntdetect.com, since the stop error (7b) is very similar to that of failed USB boot (USB bus was reset while booting). GTS drivers do work with NF4 RAID though, when system boots from other device. I hope this has cleared NF4 GTS confusion and someone with enough skills may try to find a way to circumvent boot error. That would be very appreciated.
