-
After starting the graphical installer, it gives the error:
"function probe_partition_for_geom()  failed".  I kept on clicking
IGNORE, which lead to other screans each time.

After selecting the timezone, software packages [custom] and when it
is started to copy the files from the CD, it gave an exception & hang
I was installing on Pentium-II 400 MHz.  The hard drive had around 6 GB.
