When I boot my computer with the Redhat 7 CD in, and go through the setup 
process, I get an error during the part where it creates the loopback 
system, and the computer freezes.  I am running a PC with a Pentium II 
Xeon processor and 256 megs of ram, and I am installing Linux to an 
existing FAT32 partition.  I get the following error:

Traceback (innermost last):

  File "/var/tmp/anaconda-7.0.1//usr/lib/anaconda/iw/progress_gui.py", 
line 20, in run
    rc = self.todo.doInstall ()
  File "/var/tmp/anaconda-7.0.1//usr/lib/anaconda/todo.py", line 1469, in 
doInstall
    self.fstab.makeFilesystems
  File "fstab.py", line 645, in makeFilesystems
    (self.progressWindow, _("Loopback"),
  File "isys.py", line 78, in ddfile
    os.write(fd, buf)


I was able to reproduce this error every time i tried to install Linux.  
Then, I went to www.redhat.com and downloaded the anaconda fix disk, ran 
the installer again using 'linux updates' and it came up with the screen 
saying to insert the disk, and it read updates from it.  With this disk, I 
get a slightly different error:

Traceback (innermost last):

  File "/var/tmp/anaconda-7.0.1//usr/lib/anaconda/iw/progress_gui.py", 
line 20, in run
    rc = self.todo.doInstall ()
  File "/tmp/updates/todo.py", line 1488, in doInstall

  File "/tmp/updates/fstab.py", line 645, in makeFilesystems
    (self.progressWindow, _("Loopback"),
  File "isys.py", line 78, in ddfile
  OSError: [Errno 27] File too large


I was also able to reproduce this error every time I tried to install 
Linux.
