SP4 has a new Atapi.sys that allows the IDE drive to be formated during install and to address the drive beyond 8Gig. SCSI drives are not affected with this problem.
To use the SP4 Atapi.sys during install: (Insure your System BIOS can handle drives of this size)
1. Download ftp://ftp.microsoft.com/bussys/winnt/winnt-unsup-ed/fixes/nt40/atapi/ATAPI.EXE.
2. Copy ATAPI.EXE to a blank (preformatted) diskette.
3. Run ATAPI.EXE to extract Atapi.sys. Label the diskette "MS SP4 ATAPI IDE driver".
4. Start the install from the 3 setup diskettes.
5. Press S to skip detection of mass storage devices.
6. Press S again when setup lists <none>. Insert the "MS SP4 ATAPI IDE driver" diskette and press ENTER twice.
7. Press ENTER after the ATAPI driver is listed.
8. If you have additional mass storage drivers, press S.

You are prompted for the ATAPI diskette during the copy phase of the installation.
For SBS:

2. On Setup diskette 2, rename Winnt.sif to Winnt.bak and copy Winnt.sif from the i386 folder of the CD.
3. Start the install from the 3 setup diskettes.
