This patch supports a real hard disk drive by \\.\PhysicalDriveN
(N=0,1,2,...) on Windows 2000/XP host. Windows 98/Me are not supported.
You can also use slash like //./PhysicalDriveN. You can see a number in
Administration Tools in Control Panel. This is not case-sensitive. It is
necessary to have an administrative priviledge.This can be used like this.

qemu.exe -L .\bios -hda win2k.img -hdb \\.\PhysicalDrive0

This patch also adds a size information about CD-ROM.

It is safe to use it as a read-only. Making a file from guest OS to real
disk  isn't recognized immediately. Rebooting a host OS recognized the file.
Making a directory from guest OS breaks a host's file system.

There is a case that changes of files in a host OS isn't recognized by a
guest OS. Shut down the guest OS, move the file to another directory and
boot the guest OS. Then the file is recognized.

Windows 98/Me doesn't recognize NTFS file system. When you use Windows XP on
NTFS, Windows 98/Me guest can't see host files.

If you don't have a multi-boot environment, don't boot from your system hard

qemu.exe -L .\bios -hda \\.\PhysicalDrive0

It will break your host OS.
