I am creating an unattended Windows Server 2003 installation process using WinPE 2.0. I have been testing the process on virtual systems to get the process working just the way I need it. Works perfectly every time. Moved on to one of our physical systems, an IBM x3500. Ran into some driver issues, which I expected, and integrated the drivers into my process as needed. Again, process works great on the IBM x3500. I thought I had it all figured out, until I ran the process on several of our IBM x3550 systems, the headaches began, the frustration level rose, and after a week of failure and disappointment, I gave up. Until now... My process is as follows: Boot to WinPE environment Request server information via HTA Create RAID configuration and logical drives Partition Drives Format Partitions (NTFS) Copy supporting files to system partition Initiate Windows Installation (C:\support\i386\winnt32.exe /syspart:c: /noreboot /s:C:\support\i386 /unattend:c:\support\winunatt.ini) That is the basic flow, it is more detailed by irrelevant to the issue I am having (I think). Through this point everything functions properly. At this point the system reboots, performs post, then at the point that it should boot and begin text mode setup, I get a black screen with a flashing cursor in the upper left corner of the screen. No error message. No attempt to boot any other device. I have been struggling with this problem for about two weeks now. I have tried the following suggestions found in this forum: Using "align=16065" with diskpart when creating partitions Adding the registry changes to WinPE prior to issuing diskpart reg load HKLM\PE-SYS c:\Winpe\Mount\Windows\system32\config\system Reg Add "HKLM\PE-SYS\ControlSet001\Services\vds\Alignment" /t Reg_Dword /v LessThan4GB /d 0 /f Reg Add "HKLM\PE-SYS\ControlSet001\Services\vds\Alignment" /t Reg_Dword /v Between4_8GB /d 0 /f Reg Add "HKLM\PE-SYS\ControlSet001\Services\vds\Alignment" /t Reg_Dword /v Between8_32GB /d 0 /f Reg Add "HKLM\PE-SYS\ControlSet001\Services\vds\Alignment" /t Reg_Dword /v GreaterThan32GB /d 0 /f reg unload HKLM\PE-SYS Formatting to FAT32 instead of NTFS The IBM systems I am using have different RAID controllers, but use the same drivers. The IBM x3500 has a ServeRAID 8k, where as the IBM x3550 has a ServeRAID 8k-l, Both are manufactured by Adaptec and I have obtained the latest drivers. I have also updated the firmware on the IBM x3550's RAID controller. I can successfully install Windows Server 2003 from CD using the same drivers. If I boot back into WinPE, I can browse the directory structure of the local disks and see all the files just as I should. I am stumpped! I'm sure I am missing something basic, any help would be appreciated.
