Hard disk size limits
^^^^^^^^^^^^^^^^^^^^^
There are limits to how big of a hard disk an emulated machine can accept. Such limits will vary depending on the machine's BIOS. The table below lists all important limits applicable to the IDE bus:

The maximum supported disk image size for IDE or SCSI is 131071 MB. Disk overlay software such as *Ontrack Disk Manager* can work around BIOS limits and allow booting of IDE hard drives within the 131071 MB limit, with the same caveats as using such software on a real machine.
