Yes, it seems, that it'll work with 386SX too. Here's what I've found on "cpuidle" home page: "Under normal circumstances the CPU isn't always active but spends much time waiting for the keyboard, harddisk or CD-ROM. What would be more logical than to turn off the CPU for that period? That's exactly what the HLT machine instruction (Opcode F4) does. Whenever the CPU encounters a HLT instruction the clock is halted and the CPU enters suspend mode until an interrupt, NMI, or reset happens. With the advent of power saving microprocessors like the Cyrix Cx486S the HLT instruction elicits an additional benefit. When `Suspend on HLT' is enabled in the configuration register the processor not only stops on HLT but also enters the power saving suspend mode". Of course, 386SX hasn't been designed as "power saving microprocessor" - but still, if HLT halts CPU clock, it's suggesting to me, that effectively CPU is "turned off" (until an interrupt happens). And since in DOS we've got no "daemons" running in "background", even the HLT method alone can be quite effective method of "cooling". ------------------------------------------------------------------------------ Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
