Down, boy.
Scientific Linux is behind the times on available tools, because our
favorite upstream vendor has not yet released tools. Tools to work with
have been tested, effectively, with Fedora, and I expect our favorite
upstream vendor will include tools with release 7.x, which is not
yet in
alpha or beta release. Check out
http://docs.fedoraproject.org/en-US/Fedora/18/html-single/UEFI_Secure_Boot_Guide/index.htmlfor
a good breakdown of the issues and trade-offs.
UEFI is part of the old "Palladium" project from Microsoft,
relabeled as
"Trusted Computing". It is aimed squarely at DRM and vendor lock-in,
not
security, for reasons that I could spend a whole day discussing.In the
meantime, yes, you can disalbe it for SL booting if needed, and
reasonably
expect our favorite upstream vendor to have shims available when
version 7
is publishedL they're already working well with recent Fedora
releases. I'd
also *expect* those shims to be workable for SL 7, but someone may
have to
plunk down some cash to get some keys signed, and spend some extra
effort
to maintain the security needed for the relevant shims to work well
with SL
kernels and environments.

permits
this to be disabled (I have heard of some UEFI implementations that
do not
permit secure boot truly to be disabled).
If Linux cannot handle this issue, then Linux is finished on all
generic
(e.g., not Apple that supplies both the hardware and operating
environment
software under a restrictive proprietary for-profit intellectual

license) X86-64 hardware, as (almost?) all current such hardware is
MS 8

Is "secure boot" enabled in the UEFI ?
Does anyone? Does SL6x boot correctly (and easily) on a UEFI
motherboard? If so, he may switch to SL.
Yes as long as "secure boot" is disabled .
