[FEATURE REQUEST] firewire IEEE 1394 (ohci) module

[FEATURE REQUEST] firewire IEEE 1394 (ohci) module

[Robert]

I'd like to boot from Grub into Firewire IEEE 1394 (ohci)   ;-)

Robert


PS: USB UHCI modules do already exist, but they seem to not work 
properly (v1.98)

That's one thing we don't risk having soon. Few people even have such
hardware (my laptop has no firewire connector at all). Some of my test
machines have it but I have no firewire HDD. Even fewer of these people
have required skills (it requires someone who had a similar experience
like Aleš or me). And even less have motivation. Additionally since most
of external HDDs supporting firewire also support USB, it seems pretty
pointless. So it will probably never happen.
Of course, you can back up your feature request with work (a patch, make
sure you don't include any license-incompatible code, consult before
including any third-party code) or money (by sponsoring hardware and
putting a bounty).

That's old. USB has evolved a lot since then.

the FiWi HD here has USB here too. Yet via USB the usable HD speed 
is 2x .. 4x slower on large file transfer, and it seems even 
slower on many small files.
A HD on Firewire here is quite as fast as an internal one - seen 
on two laptops. So via Firewire its feels really usable, while on 
USB its half way to Knoppix ..

(as far as Linux is concerned, currently I help me using FiWi by 
loading the Linux kernel&initrd from another device, which needs 
special updates etc.)

Note: I remember the first installation of Grub into the internal 
HD MBR while installing Debian 6 on Firewire: Where was no 
warning, but on reboot the Laptop was dead on the rescue prompt of 
Grub (which could do only 'ls' and nothing else). "error: device 
not found" or so. and even the original Windows on intern could 
not be started.

Maybe there can be added a check&warning at install time if Grub 
cannot load its own modules (which obviously remained on the 
Firewire parititition.)

If it's a permanent setup you're better off with putting HDD internally.
For Live system compatibility is often more important. So still a very
corner case where few people would be motivated.

It's not easy to check whether BIOS has firewire support.
