Is it possible to update OBP while running Debian?

[John <johnhedge@gmail.com>]

Hi list,

I've got an Ultra5 IIi 360mhz running OBP 3.19. (and Etch)

I'm trying to connect it to an A5000 mda using a Qlogic qla2200f/66. I've managed to get the Ultra/Etch to see all 14 drives but now I need it to boot to them.

Hence the subject line.

Which OBP, if any, can do the job?
If so, where can I get it?
Is there a 'howto flash OBP using Debian'?

TIA

John
