REG_DWORD |
0x400–0xFFFFFFFF (attempts) |
0x2EE0 (12,000 attempts) |
Description
Specifies the maximum number of times Windows Server 2003 polls the hardware on older-style AT keyboards. If the number of trials specified in this entry is exceeded, then Windows Server 2003 stops polling.
You might consider increasing this value if the driver does not initialize or operate correctly and the System Log in Event Viewer contains the following message from the source, i8042prt:
The operation on <driver name> timed out (time out is configurable via the Registry).
Note
- Unlike some entries in this subkey, this entry remains in the Parameters subkey and is read from this location even after a keyboard is installed.
