>Description:
I boot the computer from cd-rom,fdisk. bsdlabel,then chose custom install,everything is ok,but when chose the media,just a err:

no CD/DVD devices found

I have search the web and found someone had reported the problem:

http://www.freebsd.org/cgi/query-pr.cgi?pr=65410

but the solution is :try do disable some device...

so I do,no use,then try fb 6.0 release
still the same
then fb 4.11 release.
just the same

then I want to see if there is some hardware problem.
so I try to install ubuntu 5.1 on the same computer,everything is ok.
