i think it's worth compiling in. I use it myself too and never had any problems with it. from the kernel help section: On Intel P6 family processors (Pentium Pro, Pentium II and later) the Memory Type Range Registers (MTRRs) may be used to control processor access to memory ranges. This is most useful if you have a video (VGA) card on a PCI or AGP bus. Enabling write-combining allows bus write transfers to be combined into a larger transfer before bursting over the PCI/AGP bus. This can increase performance of image write operations 2.5 times or more. Saying Y here creates a /proc/mtrr file which may be used to manipulate your processor's MTRRs. Typically the X server should use this. > Cheers, > Mark > > > -- > [EMAIL PROTECTED] mailing list -- Stijn Vander Maelen <[EMAIL PROTECTED]> Infogroep -- [EMAIL PROTECTED] mailing list
