Switch GRUB4DOS to use APM or ACPI

Hi. I like G4D but on my ThinkPad X61 in any virtual machine G4D use 100% CPU. CPU temperature is high and the fan noise strongly.
In DOS use tools IDLE.COM or FDAPM:

LH FDAPM APMDOS

Please read this blog's to understand what I mean:
 
Why does DOS use 100% CPU under Virtual PC?
DOS guest in VirtualBox is heating up the host machine

Is it possible to do something to G4D using APM?
Thx.

Grub4dos will need to be modified. You can submit a request here:

OK, I submitted request on https://github.com/c...b4dos/issues/89

It is a known problem.

 

It could be solved by adding a HLT instruction within the getkey loop.

 

But the HLT instruction will cause other problems.

 

Some hardware virtualization softwares will hangup at a HLT instruction. Grub4DOS cannot successfully boot up under those virtualization softwares.

 

I think you should ignore this problem.

On other computers where CPU fan runs at a constant speed in fact no problem and can be ignored.
The most bothered when using the G4D command line.

Last time I ran grub4dos in Qemu (actually Qemu Manager) the VM usage stayed at 50% CPU load, maybe it applies to VirtualBox only (or on your specific ThinkPad only)

grub4dos is just a bootloader. it is not an OS. most people, in most cases,
only use it to boot up an OS, such as Windows and Linux. people seldom work under
grub4dos for a very long period of time.

On the other hand, it is important for a bootloader to work fine in various environments.
A bootloader should avoid hangups as long as possible.

Yes, you are absolutely right and probably better to ignore the problem. To learn G4D commands better to use a different, quiet computer e.g. fanless Thin Client :-)
