[Partitioning Systems] intel: Found GPT signature, ignoring.

hrev56019 x86_64 uefi.

I got a laptop from work with preinstalled Windows 10 and MBR partitioned HDD. When I boot Haiku off a USB drive DriveSetup doesn't list this HDD. It looks like intel partition add-on ignores it because it found GPT signature: ​https://cgit.haiku-os.org/haiku/tree/src/add-ons/kernel/partitioning_systems/intel/PartitionMapParser.cpp#n329

There is a valid GPT table, which looks like it was successfully read and contains valid partitions. I'm not sure why we would consider the Intel partition map? What is the problem here?

It looks like the NVMe controller is in RAID mode (class_base 01, class_function 04), no driver for this. The FreeBSD driver for this is named ​vmd and looks like a PCI bridge.
