I read from an article (Google search) about a company named OCZ that presented recently at Computex a Firewire key,
it looks like an "USB" key (stick) but its connects through the Firewire (IEEE 1394) interface (6-pin). Is it interesting?
The performance (throughput in read/write MB/s) is a little better than USB 2.0. But the problem is that PC/laptop not-MAC does not seem to be able to
boot from Firewire (no BIOS function), and on laptops the Firewire plug is usually 4-pin, that is to say no 2 power pins, so it is a problem.
The USB 2.0 plug (either A or B or mini-A mini-B ) includes power so it is really handy for USB key and 2"5 HDD with low
energy consumption (500 mA).

Questions (kind of brainstorming) :
1) Why BIOS on PC world does not support Firewire boot?
2) In the future there is also Wireless USB2. I do not know the impact on BIOS, or booting process.
3) PXE (network boot). Currently it seems to be only Ethernet. It is possible to boot from WiFi (802.11a/b/g/n)?
4) There are external CD/DVD-ROM drives connected through both parallel port (very old days), USB2 or Firewire, or PCMCIA/Express Card.
Any technical problems booting from these CD/DVD?

Well, on the old bootable media, there is LS-120 super diskette (and Iomega Zip drive on parallel port with some software tweaks).

Don't know all the answers to the topics you've mentioned - nor I'm absolutely sure which are the best solutions but I can share some of my experience if you like.

#1 - Don't think people designed Firewire to be used as boot device - but there are some promissing changes regarding BIOS and *maybe* in the future some barriers regarding the use of this device are removed.

Some hope:


#2 If #1 is replaced with an open architecture this should also be solvable.


#3 At the moment it's isn't as far as I know it - asked the same question some time ago here: http://www.911cd.net/forums//index.php?s=&...st&p=129552

Dunno about pxe over wifi, wifi nic needs to support pxe protocol but I don't known
if some manifacturer implements it, then I doubt the ntloader will detect the wifi card as network
card and the normal network stack is not enough, it needs to use wep/wpa or no encryption at all
but it still need to handle the AP. I'll search something around



#4 Ultra portable laptops like the ones from Sony Vaio don't usually come with CD drives - I have one of those since 1999 and it uses PCMCIA to interface with the external CD drive. It is also able to boot from PCMCIA so I guess it depends on the manufacturer.


Hope this helps you.. (IMG:../forums/style_emoticons/default/cheers.gif)

No idea, but at least M$ considers Firewire as host for Windows. Else they wouldn't already support Firewire during text based setup.
