Is my understanding correct that QEMU actually does nothing with RECHS except
poke a magic number into CMOS memory when x86 guests start?
(I ask because we don't even use the constant:
$ git grep _RECHS
include/hw/block/block.h:#define BIOS_ATA_TRANSLATION_RECHS 4)
Please also add changes for:
blockdev.c:
QemuOptsList qemu_legacy_drive_opts = {
...
},{
.name = "trans",
.type = QEMU_OPT_STRING,
.help = "chs translation (auto, lba, none)",
},{
qemu-options.hx:
Force hard disk 0 physical geometry (1 <= @var{c} <= 16383, 1 <=
@var{h} <= 16, 1 <= @var{s} <= 63) and optionally force the BIOS
translation mode (@var{t}=none, lba or auto).
