I can recall a longer time ago I asked a question about this, and the tip was to use "FDAPM ADV:REG".
Unfortunately it seems FDAPM most probably supports only APM, which isn't present in BIOS-es of (most of) post-2000 motherboarda anymore. When I get its status by simply typing "fdapm" it answers: #v+ Found resident FDAPM / POWER driver version 1.0 Savings mode: BIOS APM plus interrupt hooks (REG setting) CPU was idle 0% of the time No APM information - no APM 1.x BIOS? #v- I'm afraid the above means that power-saving feature doesn't work for me at all? When I run OpenBSD's "dmesg" on the same mobo, it reports: #v+ acpi0: sleep states S0 S1 S4 S5 acpi0: tables DSDT FACP APIC ... acpicpu0 at acpi0: C1(@1 halt!) #v- So its BIOS has ACPI-based power saving ability, but can I take any advantage of this under FreeDOS' control? -- regards, Zbigniew _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
