I guess you mean "can't access the CD". A useful trick is
to copy all the rpm files to your hard disk, and then do
a hard disk install. You need to partition your hard disk
first to do this.
Also, you could try the Zipslack distribution. It comes
as a zip file, and you only have to unzip it onto a
DOS or Windows partition and then you can boot into
Linux using loadlin. It comes with a FAQ that tells
you how to move your filesystem over to a new ext2
file system, because Zipslack installs as a UMSDOS
file system. Zipslack comes as a complete installation,
except for X. It is the easiest way to install Linux
that I have tried.
