According to the sticker on the bottom, this model was made in 04/2000, so the 6 years is right. > We're talking here about a system from 1999 where Windows 98 refuses > to run in ACPI mode and instead runs in APM mode. I haven't tried Windows 98 on this machine, but Windows 98SE would run in ACPI mode if it weren't for a cheap hack by IBM. The latest BIOS (1.11), which I'm using, claims to be from 1999. However, that date is almost surely wrong. The readme/changelog with the BIOS update diskette is dated Sept 20, 2001 and contains this note about the 1.01 update: - (Fix) If Windows 98 Second Edition is installed as APM mode and an updated BIOS is installed with a BIOS date 12/02/99 or later, Windows 98SE will change the mode from APM to ACPI whenever a New hardware profile is created. So this BIOS set the date to 11-30-99. Probably IBM marked all the BIOS dates as 11-30-99 in order to work around this W98SE misfeature. My guess is that BIOS 1.11 is really from Sept 2001, or 4.5 years ago. Old, but not octagenerian! > I consider that it works in ACPI mode at all as "miraculous":-) Amen to that. I was very pleased when the combination of newer ACPI releases plus my modifying the DSDT made S3 work. > I do think the issue merits investigation ... Although I have little idea of what sections of code to modify, especially since the commit in question merges two well travelled branches, I'm happy to test patches. -Sanjoy `Never underestimate the evil of which men of power are capable.' --Bertrand Russell, _War Crimes in Vietnam_, chapter 1. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
