Trying to Install OES on a brand new DELL PowerEdge 2850,

What I did:
On first boot, went to PERC (Power Edge Raid Controller) Configuration utility (^M)
Cleared Configuration, then choose New Configuration.
Selected all four hard drives: set A-00 field to "Span-1"; and changed RAID 5 to RAID 0,
and saved config.

Then initialized the single logical drive. Progress bar went from 0% to 100%.

Then rebooted with CD 1 of OES and continues with first stage of installation.
at this point I'm getting this error message:

"Error occurred while copying packages from the source CD to the
disk cache".

Any idea about this error message, it's the firrst time I get this error.
any idea appreciated.
