No ACPI-table found, option -M 1.6 not found either
Currently writing a small kernel, when trying to detect memory blocks that contain ACPI information, no such block is found. When ran in Oracle Virtualbox, code runs flawlessly.
Code that is detecting the ACPI-Info (with a bit of debug-output):
```
multiboot_memory_map32_t* map = (multiboot_memory_map32_t*)mmap;
for (uint32_t i = 0; i < size; i++) {
Termutils::cout << map[i].type << "type of block ";
if (mmap[i].type == MULTIBOOT_MEMORY_ACPI_RECLAIMABLE) {
Termutils::cout << "WE ARE INSIDE\n";
fadt = (FADT*)(map[i].base_addr_low);
//break;
}
if (i % 9 == 0) {
Termutils::cout << "\n";
}
}
```
command qemu is run with:
qemu-img create build/objects/test 500M
qemu-system-i386 -hda $(APP_DIR)/clinl.iso -hdb ./build/objects/test
The iso-image is (zipped) included as attachment.
