[edit]Windows 3.1 CPU
[edit]Is there a way to add HLT to Windows 3.1 in standard mode (not 386-enhanced mode)? 82.44.76.14 (talk) 19:20, 19 October 2013 (UTC)
- It's a privileged (ring 0) instruction. I haven't worked with Win 3.1 for a very long time, but you may have to write a device driver or similarly elevated-privilege module to be able to use this instruction.-gadfium 01:28, 20 October 2013 (UTC)
- I assume you know about WQGHLT, which does what you ask for in 386-enhanced mode. Have you tried DOSIDLE? I am no expert on Windows 3.1 in standard mode, but as far as I understand that should be worth a try. --dapete 14:06, 20 October 2013 (UTC)
