Many people +have suggested using chain.c32 to chain load the local disk as a workaround, +but this causes problems with Windows 7 BitLocker as it detects the chain load +and forces the user to enter the recovery key. While searching for another +option I determined that the problem seems to stem from the BIOS storing some +information in the memory range 0x47CC-0x47FF, which is overwritten when +PXELINUX loads. I couldn't figure out a clean way to avoid that memory region +as it falls in the middle of the 4.x bss16 region, so I decided to create a +copy of it instead. By copying that information out of the way during PXELINUX +initialization and copying it back before returning control via 'localboot 0', +the computer successfully boots to the local disk. + +Some additional info: + +BIOS revision: A13 +PXE versions: Intel Boot Agent GE v1.3.81, Intel Boot Agent PXE Base Code (PXE-2.1 build 089) +Versions of SYSLINUX affected: 3.83, 4.03, 4.04, 4.05, possibly others +Resulting symptom for localboot option vs SYSLINUX version: + + localboot 0 localboot -1 +3.83 Reboot Reboot +4.03 Reboot Reboot +4.04 Hang Reboot +4.05 Hang Reboot + +This patch does not fix the reboot issue when using 'localboot -1'.
