From bda055096be9a91d602af457f8bedeede86eb3f6 Mon Sep 17 00:00:00 2001 From: Roman Kagan Date: Wed, 17 Feb 2016 21:25:31 +0300 Subject: [PATCH] i386: expose floppy drive CMOS type Make it possible to query the CMOS type of a floppy drive outside of the source file where it's defined. It will allow to properly populate the corresponding ACPI objects and thus enable Windows on BIOS-less systems to access the floppy drives.
