Hi Shane, I read your suggestions about hunting that FreeCOM bug where it stops running programs, sounds good :-) Did you find a clue yet? Yes! Please see my next post. Norton Text Search (ts.exe) prints about four characters a second when FDAPM APMDOS is running. Setting FDAPM APMOFF fixes this. This may also affect other Norton Utilities. ... The workaround is to use FDAPM ADV:REG instead of FDAPM APMDOS which keeps most of the saving but ignores int 28 :-). Please let me know if it also helps with your Norton Text Search / TS problem.

Hi Shane, I read your suggestions about hunting that FreeCOM bug where it stops running programs, sounds good :-) Did you find a clue yet? Norton Text Search (ts.exe) prints about four characters a second when FDAPM APMDOS is running. Setting FDAPM APMOFF fixes this. This may also affect other Norton Utilities. I suspect it's because FDAPM hooks an interrupt for power saving use that Norton was already using for something. In my previous post that (the non-bug reports) that referred to Norton Utilities, I was not running FDAPM. What FDAPM does is that it waits for the next IRQ when the pattern of int calls suggests that the apps and kernel are also only waiting for something. I remember one case where FDAPM APMDOS was too strong and caused a delay: This was related to Novell DOS and int 28 idle calls. The workaround is to use FDAPM ADV:REG instead of FDAPM APMDOS which keeps most of the saving but ignores int 28 :-). Please let me know if it also helps with your Norton Text Search / TS problem. Note that using APMOFF or APMBIOS only gives minimal savings as they only tell the BIOS to go to energy wasting but high performance or normal mode respectively, without doing anything specific to DOS.

I suspect it's because FDAPM hooks an interrupt for power saving use that Norton was already using for something. Try FDAPM APMBIOS. Does it still affect the program's performance? APMDOS hooks too many interrupts. Regards, Christian -- ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
