Gentoo on non bootable drives

[rsobba at kcnet.com]

Is anyone familar with how to install Gentoo on a PC where the bios does 
not support booting from the CD - drive? I have created an bootable 
diskette in Redhat but am unable to find any info on the web including the 
Gentoo site. And on a related subject does anyone know how to copy the 
data base or file containing all emails within Evolution? I have many 
saved e-mails from this group and would hate to loose them, if it makes 
any difference I currently use Mandrake 8.0

Thanks!
