Insyde Technology's keyboard controller and scanner firmware for the Renesas H8 family of keyboard/embedded controllers, is compatible with the industry-standard 8042 interface and can scan a locally defined OEM keyboard matrix. It simultaneously supports a scanned keyboard, external keyboards, and PS/2 mice. Options are also available for battery charging and monitoring firmware. KeyPRO is also fully functional in ACPI (SCI) or legacy (SMI) environments.

Full ACPI Compliance

The ACPI Embedded Controller Interface Specification (Chapter 13 of the ACPI specification) requires either three separate host interfaces (KBC, SCI, SMI) or two interfaces (KBC, and shared SCI/SMI). If shared SCI/SMI is used, the ACPI Global Lock Mechanism must be employed to avoid contention between SCI and SMI environments. Use of the Global Lock Mechanism could result in system performance degradation.

Insyde Software's EC eliminates this problem via it's "Virtual Host Interfaces" feature. When used with Insyde Software's BIOS, multiple environments (ACPI, SMB BIOS, SMI) can freely share the EC's internal and SMB resources. This provides OEM greater control over the system and freedom from Global Lock implementation and system overhead concerns.
