DOCUMENT:Q129119 08-AUG-2001 [winnt] TITLE :Unable to Set Typematic Rate on AT&T Globalyst PRODUCT :Microsoft Windows NT PROD/VER: OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 3.5 - Microsoft Windows NT Server version 3.5 ------------------------------------------------------------------------------- SYMPTOMS ======== Under Windows NT 3.5, you are unable to set the typematic rate on a 90 mHz AT&T Globalyst 600 (3356) Pentium ISA/PCI. Changing these settings in the CMOS or in Control Panel has no effect. NOTE: The AT&T Globalyst 600 (3356) Pentium ISA/PCI in on the December 1994 Hardware Compatibility List (HCL). The NCR H0150-STD1-12-17 and 3299-K440- V003 are the standard keyboards for this computer. CAUSE ===== The problem appears to be related to the speed of the machine. Slower machines with the same keyboard work fine, but the 90mhz machines fail consistently. MORE INFORMATION ================ The initialization code for i8042prt sends a control byte to the keyboard controller to set the typematic rate and the keyboard indicator lights. It then waits a preset, but arbitrary, amount of time for a return. If no return is received, a message is posted to event viewer and initialization proceeds. The waiting period is not configurable through the user interface or the registry. The Events posted include: Event ID 19: I8042_SET_TYPEMATIC_FAILED Message Text: Could not set the keyboard typematic rate and delay. Status: 0xC0050013 Event ID 20: I8042_SET_LED_FAILED Message Text: Could not set the keyboard indicator lights. Status: 0xC0050014 STATUS ====== Microsoft has confirmed this to be a problem in Windows NT version 3.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
