How to install under a SATA disk?

[Han Chunwei]

Hi,
I have two questions to ask:
1. The cpu of my computer is AMD Athlon64 2800+, which distribution
should I use?32bit or 64bit?
2. The hard-disk is of SATA type, and I can't install the system from
hard-disk(I don't have a CD-Rom). I have tried every method to do this
and failed. I nearly got despaired.
Please figure out a way to solve the problems. Thank you!
