This means all of memory is available, but one still needs to be careful about segment usage. SeaBIOS always calls the option roms with a %ss == %ds == 0, but I don't think it is wise to rely upon that. So, it's better to use GET_FARVAR(0, *(vp+VP_MISC)). -Kevin

Please help! Unfortunately, it's very difficult to debug acpi issues on Windows. Gerd's been on vacation this week - so, lets give him a chance to look at it when he gets back.

Unfortunately, I haven't been able to find out why the debug macro fails on these older versions of Windows. -Kevin

[SeaBIOS PATCH 0/2] Allow non-contiguous APIC IDs (v3)

[PATCH 0/6] Build PCI hotplug SSDT from a single template
by Paolo Bonzini 01 Aug '12

01 Aug '12

More than 1kb of data is taken by the 32 copies of the PCI hotplug SSDT methods. We can build them from a single template like we do for CPUs. This series does exactly this. Patches 1 and 2 prepare for the change, by moving other pieces of ssdt-pcihd.dsl out of the way. Patch 3 is also a simple rename and patch 4 fixes a bug in acpi_extract. Patches 5 and 6 finally do the movement. Paolo Bonzini (6): acpi: move PCNT to DSDT acpi: move s3/s4/s5 to build_ssdt acpi: rename Processor SSDT constants acpi_extract: fix off-by-one acpi_extract: detect DeviceOp acpi: build PCI hotplug devices from a single template Makefile | 2 +- src/acpi-dsdt.dsl | 39 +++++++++++- src/acpi.c | 161 ++++++++++++++++++++++++++----------------------- src/ssdt-pcihp.dsl | 124 ++++--------------------------------- src/ssdt-susp.dsl | 41 +++++++++++++ tools/acpi_extract.py | 30 ++++++++- 6 files changed, 206 insertions(+), 191 deletions(-) create mode 100644 src/ssdt-susp.dsl -- 1.7.10.4

Yes, for whatever reason, it is definitely an issue with the newer version of bison.

This looks like it may be a Bison issue, since the file "aslcompilerparse.h" is in fact an intermediate file created by Bison. With Bison version 2.4.1, there is no declaration of "AslCompilerparse" within the aslcompilerparse.h file. Could you try an earlier version of Bison?
