FreeBSD-RELEASE-5.2.1-ia64 installation problem

[Mogilny I. Aleksandr]

Hello,
I have a subject problem. I have downloaded all iso files from ftp site, 
written them with burncd on othe unix machine (FreeBSD-4.9) but any of 
cd didn't boot. I also tried to burn CDs with nero with option cd copy 
but that also didn't help. Distribution contains no  floppy images. Why? 
I didn't know what else to do and decided to use i386 5.2.1 RELEASE's 
images it installed the operation system (during installation i told sysinstall 
to llok for distribution on one of the local computers near me) but it didn't 
boot (couldn't load kernel at startup). I gess this action of mine wasn't 
correct. What else can i do to install this release?
Thank you for further help.
