https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276463 Peter Grehan <grehan@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |grehan@FreeBSD.org --- Comment #4 from Peter Grehan <grehan@FreeBSD.org> --- This is due to memory being detected from CMOS bytes, which limits the maximum amount of RAM to 1TB. This appears to be leftover code imported from the original UDK2014 bhyve EFI code, and was removed in OVMF with this commit: https://edk2.groups.io/g/devel/message/80822 The fix would be to use the E820 map instead of CMOS in Bhyve/PlatformPei/MemDetect.c -- You are receiving this mail because: You are the assignee for the bug.home | help
