Mon 26 Mar 2007 09:21:25 PM UTC, comment #1: It was brought to my attention that the nocopy patch may not work on some systems. This patch supercedes that one. It loads the initrd in 1MB increments. This way it will avoid trashing BIOS reserved memory and also will not pose a problem for systems with large memory where the operation reading directly from disk may not be able to access the upper memory regions. |

When grub reads in an initrd that is larger than ~13MB, it overwrites a memory region that is reserved by the system BIOS in some systems.
