I'm a bit new to this forum so please forgive any obvious misconceptions I may have about RIS, which mostly I love. I have been running an Unattended RIS install for XP for a couple of years with great success. The IT staff just love it, however I have been lumped with a Dell Precision 490 with Intel Serial ATA Raid that just ain't workin. After I complete the interview normally Windows Text Mode setup launches and away she goes. Not this time. I have had the same trouble with a Poweredge 2850 with a SCSI Raid card, so it looks as though RAID is the issue but I have trawled the net for solutions including a number of attempts at textmode setup and still I can't get the thing to work. I tried Bashrat's driverpack and integrated the drivers into i386 and loaded a new RIS image onto the RIS server, still no good. I switched off OemPreinstall=No so that I could get the F6 prompt and run it via floppy just to get over the glitch, but I don't even get to that section of the installation. I have spoken to Dell Gold Support about it but it doesn't sound like they are familiar with the problem. So now I turn to the real experts out there. Have any of you seen this problem and even more important have you found a solution?
