Description John Reiser 2009-09-20 04:46:50 UTC 
Description of problem: The i686 (i386) installer uses at most 3.3GB of RAM because it runs "kernel" instead of "kernel-PAE".  If used, then the currently-ignored RAM would decrease install time by increasing available buffering.


Version-Release number of selected component (if applicable):
anaconda-12.26

How reproducible: every time


Steps to Reproduce:
1. boot installer on i686 with PAE and 4GB of RAM (or more) installed
2. switch to FT2 as soon as possible
3. sed 1q </proc/meminfo
  
Actual results:
MemTotal:        3320564 kB    # approx 3.3GB

Expected results:
MemTotal:        4058316 kB    # on box with 4GB installed


Additional info: Actual numbers depend on BIOS and hardware installed.

Unfortunately, the kernel-PAE kernel does not work on all the machines that are supported by Fedora.  If we wanted to implement this, we would then need to offer multiple kernel entries in the boot.iso menu, etc.  That then pushes a complex and hard-to-explain decision off onto the user to pick the correct kernel.
