Description of problem:
Anaconda reports that it is short by -7k bytes to install the system.  This is a fresh install of RH 7.1.  The disks have installed on ther systems 
without any trouble (ide based system).  This system has both ide (win 9x) and SCSI (adaptec 2940uw) drives.  This was attempted to be 
installed on a 4 gb SCSI hd. Swap was on a different SCSI drive.  There are two exsisting (ext2) fs's that were not formatted, but defined in Disk 
druid.  There are 4 win9x partitions (ide  / SCSI) on the system.

Here is the crash file:

Additional info:

used expert startup  for I didn't want to lose current ext2 filesystems
I would like to install RH 7.1 instead of RH 6.2 (6.2 was the old system before ide HD install).
