From: mac on 1 Aug 2006 18:28 In a Windows Crash Report, it says to disable BIOS Caching or Shadowing... So I did. What is the downside of doing that? I don't know what these features do. Will impact performance? Thanks, mac

BIOS is cached into RAM, so that that code does not have to run from the BIOS storage chip. So there are two things you should know: 1. Modern BIOS chips are not that slow 2. Windows software does not ever touch BIOS program code (VGA BIOS code maybe, tho even that is unlikely) In other words, the downside is not noticeable on modern systems. -- Primary function: Coprocessor Secondary function: Cluster commander http://www.thought-beacon.net Pay once per lifetime webhosting: http://farcomm-it.com/?ref=jsah We are the paragon of humanity.

Windows software does not ever touch BIOS program code (VGA BIOS code > maybe, tho even that is unlikely) Depends what you mean by "touch" and "bios". Most modern versions of Windows certainly do read the IRQ table from system bios, along with several other settings. And it can also cause bios writes in some cases (e.g. when hardware config changes are made in a system, Windows will set the bios' ESCD flag if "PnP OS" option is selected).

Thank you all, I went ahead and re-enable these options... mac |
