Subject: Re: [PATCH v2][EFI] Run EFI in physical mode
Date: Thu, 13 Jan 2011 16:38:38 +0000 [thread overview]
Message-ID: <20110113163838.GA21289@srcf.ucam.org> (raw)

We're seeing issues with some Dell hardware when EFI is run in physical
mode - it seems that Windows uses virtual mode, so the physical path is
never exercised. I'm not sure that changing the default to physical is
going to be possible without compatibility issues.
