順便一提
Debian-Installer beta 2 釋出了,要安裝debian的朋友可以去測試一下喔!
我測試了一下,他有自動偵測硬體的部份,但是似乎對我的pcmcia方面偵測會有問題。
用usb安裝的內容我順便貼一下好了
2.3 USB memory stick
It's also possible to install from removable USB storage devices. For
example a USB keychain can make a handy Debian install media the you
can take with you anywhere.
The easiest way to prepare your USB memory stick is to download
hd-media-image.img.gz, and use gunzip to extract the 128 MB image from that
file. Write this image directly to your memory stick, which must be at
least 128 mb in size. Of course this will destroy anything already on the
memory stick. Then mount the memory stick, which will now have a FAT
filesystem on it. Next, download a Debian netinst CD image, and copy that
file to the memory stick; any filename is ok as long as it ends in ".iso".
Alternatively, if you're using linux and familiar with loopback mounting,
it can be quicker to loop mount the disk image, copy the iso into it, and
only then write the complete image to the memory stick.
There are other, more flexible ways to set up a memory stick to use the
Debian installer, and it's possible to get it to work with smaller memory
sticks. This web page has more complete directions for using
debian-installer and a bootable USB stick:

2.3.1 Booting directly from USB storage
Some BIOSes can boot USB storage directly, and some cannot. You may need to
configure your BIOS to boot from a "removable drive" or even a "USB-ZIP" to
get it to boot from the USB device. The web site above has more information
and some helpful hints about booting.
2.3.2 Using USB storage and a boot floppy
The debian-installer can be booted off a single floppy, which will be able
to access your USB memory stick. To boot the installer this way, you will
need to put the bootfloppy-image.img on a floppy (see section 2.2).
Now boot from the floppy with the bootfloppy-image on it. It should detect
your USB device and proceed with booting from it.
看來似乎可以用兩種方式一種是直接用usb隨身碟開機,另一種是利用軟體開機直接去抓usb隨身碟。
