Re: Re: T-Resc on USB

Maybe new ones, but many system, even though they have newer
processors, the general system design and bios is older and have
issues with usb HD boots.

I have seen this quite a bit firsthand. Particularly when dealing with
semi-embedded type systems, running low voltage versions of CPU's or
SOC's rather than the latest top speed heat generators. We do most of
our test booting/configuration off of USB sticks during configuration,
for later deployment on IDE-Flash modules. We often have to format our
usb sticks to mimic zip cylinder count etc before being able to
successfully boot them.

A handy utility to do this is the USB key formating program available
for download from HP (windows program).

Most of the same BIOSes have no problem booting smaller USB sticks
(512 mb and smaller) as it seem they were mostly designed at the time
these BIOSes were designed and are already formatted this way.
