Does this really help you? > SHELLHIGH=C:\RECURSOS\4DOS\4dos.com C:\RECURSOS\4DOS /P=C:\fdauto47.bat Does it make a difference to use SHELL without HIGH or to use FreeCOM, for memory and idleness purposes? > loadhigh DISPLAY con=(EGA,,1) > MODE con codepage prepare=((850) C:\RECURSOS\FONTTELA\sanse_38.cpi) > loadhigh MODE con codepage select=850 A user of codepages :-) With a custom font? > Shsurdrv /D32M$Disco_Virtu Nice ramdisk :-) > DEVLOAD /H C:\FDOS\UIDE\UIDE.SYS /S25 /H /PM If you use UIDE, did you try loading it earlier? Not sure what the docs recommend about relative loading time compared to EMM386, though... > loadhigh C:\RECURSOS\4DOS\kstack.com A command history? Or just more keyboard buffer? The former is built-in with FreeCOM and for the latter you could try a FDCONFIG option, see the docs of the kernel (fdconfig.txt?)... > loadhigh c:\FDOS\BIN\keyb.exe br,850 MKEYB could also be interesting - it is tiny but only has a selection of built-in layouts. > loadhigh c:\fdos\bin\FDAPM.COM APMDOS FDAPM is small in RAM, so you can try if it works more efficiently outside UMBs. >> Does this also happen with a clean boot (no drivers loaded)? > > Yes.

Does the ThinkPad use any fancy BIOS stuff such as extra energy saving or USB-to-PS2 or similar BIOS based drivers? > Another intriguing fact is that I've already seen -- albeit very > rarely -- high numbers on the notebooks such as 90%, and low ones > on the desktops such as 3%. That is indeed unusual. It sometimes happens when software has idle loops which are not supported that well by FDAPM, e.g. SSH2DOS or other networked software, but if you mean very different idle ratio even with the same software then it is of course unexpected :-) How idle you get in part depends on which IRQ sources are active on your system and in part on what your BIOS does and whether you have hardware energy saving such as CPU throttle. > Could this be related to BIOS power management, > such as HDD power down, system doze, standby, > suspend, etc? Is the "FDAPM stats" > calculation influenced by these? It could be that standby / suspend confuses the statistics, but HDD power down is mostly done by your harddisk itself, the BIOS only sets a timer inside the harddisk one time for that. As said above, doze can have an effect if the system already "takes away CPU time" in other ways if the system is not busy. Then there is less work to be done for FDAPM but that is ok.
