Configure Protected-Mode Hard Disk Interrupt Handling

This switch allows Windows to terminate interrupts from the hard disk controller, bypassing the ROM routine that handles these interrupts. Some hard drives might require that this setting be disabled in order for interrupts to be processed correctly. If this setting is disabled, the ROM routine handles the interrupts.

Open your registry and find the key below.

Create a new Binary value, or modify the existing value called 'VirtualHDIRQ' using the settings below.

Settings:
System Key: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem]
Name: VirtualHDIRQ
Type: REG_BINARY (Binary Value)
Value: (00 00 00 00 = disabled, 01 00 00 00 = enabled)
