RHEL 5.3 Boot Error

linuxawy-awy · 12-27-2010, 07:25 AM

On our system with RHEL 5.3 , the following 2 error messages displayed during boot

PCI: BIOS Bug: MCFG area at e0000000 is not E820-reserved
PCI: Not using MMCONFIG.

and although the system is displaying that error, it works normally
it is taking some time to boot

can any body help me to discripe what is the meaning of that error and from where it is comming

Where does it say that it's an error? Looks fine to me. Bioses often work in slightly odd ways so code deals with this.

Read this Bugzilla thread. Evidently this problem is fixed in RHEL 5.4 for bare-metal, non-xen kernels.

Thank you guys for your reply.
what i understand here is that warning error is because my computer is not using hypervisor. and the fix made in RHEL 5.4 is by patch to silence MMCONFIG warnings under linux.

is my understand is true? .
