You may have used Dell's installation utilities, which would have loaded the appropriate drivers for you. You cannot use that process here. I would suggest nLiteOS.com.
I have a T110 / Perc s100/ Raid 5 (3 drives). Ctrl-R shows degraded array, single disk failure/offline. Server 2003 appears to boot normaly, instead results in blank screen with working mouse arrow in both normal and safe mode.  Is an array rebuild still possible once I replace same part no. HDD? Is the bad boot due to degraded array?
