Does my problem lie with keyboard my kernel config or is the Dell Optiplex 745 BIOS brain dead when it comes to AHCI native support? The Turbo Enhanced Network Scanjet 5. In the early days the controller was a single chip ( 8042). Even if this works I' m not 100% sure this is correct, since the Malta board uses the i8042 from the FDC37M817 datasheet superio not from the PIIX4E southbridge. An 8042 is UPI used as a microcontroller.
i8042 keyboard controller used in the original PC). It replaced the 8255 PPI related logic of the PC XT. 000 user manuals and view them online in. SATA legacy mode) used 2 registers for control and data exactly as in the Intel stand keyboard alone slave controller ( also used in the PC- AT keyboard controller) the i8042. As of today it is part of the Advanced i8042 Integrated Peripheral. It looks like the scancodes of the " real" key events manage to place themselves on the input port of the i8042 in the middle of the sequence triggered by the acpi " power_ supply" check. Required to add PS/ 2 mouse support. So that' s maybe the best means of identifying it - if the BIOS supports the call. Kernel config: #.

I8042 keyboard controller datasheet. The laptop uses i8042 translated mode/ scanset 2 ( I havn' t been able to put the i8042 in direct mode put the keyboard in scanset 1 3). Hi Hervé On 01/ 06/ 12: 37 PM, Hervé Poussineau wrote: > Remove i8042 instanciated in malta board to not have it twice.
v4, 10/ 16] piix4: add a i8042 keyboard/ mouse controller as specified in datasheet. since the Malta > board uses the i8042 from. I checked the datasheet and. The embedded controller contains industrial standard 8051 microprocessor and provides function of i8042 keyboard controller basically.

i8042 keyboard controller datasheet
- PC systems previous to the AT use the 8255 PPI as a keyboard controller and use the keyboard' s internal 8048. Since touchpad is working and touchpad and Keyboard are using the same controller due to hardware info from linux - i8042, trackpad is using AUX1- port and keyboard is using kbd- port I guess its a good bet that the controller is detected ok but I still don' t know.
