Firstly, please don't cross post to three lists, especially a developer
orierntated list alongside -newbies and -questions.

Safe mode forces PIO mode (disabling the use of DMA) and disables write
caching for all IDE hard drives and CD ROM drives, disables the probing
of EISA slots (as very few systems have them), and in i386 it also
disables the use of ACPI and the APICs.
