	=== Keyboard Error 60h or 61h ===		=== Keyboard Error 60h or 61h ===

	~~This~~ POST ~~code~~ error ~~occurs~~ on the first boot ~~after the computer has been turned off for more than a few minutes~~. The ~~problem is~~ the P82c59A-2 interrupt controllers. These controllers are easier to source ~~at a lower~~ cost~~. Downside is that you will be getting a 60h or 61h POST code on the first bootup. Hitting~~ the ~~restart button works~~. ~~If this is a problem you would like to fix then you can upgrade~~ to the AMD P8259A controllers~~. The AMD~~ chips are hard to come by and when they are available usually cost $9-10 for the pair ~~but do seem~~ to ~~fix this issue~~.		These POST error codes occur on the first cold boot. This is normal. The current BIOS does not fully support the Intel P82c59A-2 interrupt controllers. These controllers were chosen for the kit because they are easier to source in large volumes and reduce the overall cost of the kit. Upgrading to the AMD P8259A controllers permanently fixes the problem however these chips are hard to come by and when they are available usually cost $9-10 for the pair. I will work on bringing this to the attention of the community so the BIOS can be fixed. Current workaround is to restart the computer on the first cold boot.
