Other changes

 * "Suspend" button has been added to Start menu.

 * The sidebar has a chance to appear empty if Setup is started under Windows 95 or earlier builds of Windows 98. This does not occur if started from MS-DOS or Windows 3.1x.
 * At the end of the first part of setup, a General Protection Fault caused by setup in the kernel at 0001:50BB may occurs.

ACPI
ACPI support is in very early development and crashes easily. Turn off ACPI or setup can crash during hardware setup (used in early builds for ACPI errors).
