The catch is that indeed _for W98_ hibernation does work OK (because AFAICS Win98 fiddles with the BIOS hibernation setting), but in case of multi-booting other OS-es on the same Lib it does not work for them (because they do not know about Win98's fiddling with the BIOS). So if you just run Win98 on your Lib, don't bother. On my Lib, where I run several operating systems, this pwrsave.vxd bug/"feature" is a big PITA. Those OS-es which have hibernation built-in, like Win2000 and Linux kernels later than 2.4.21 properly patched with swsusp, don't suffer either. But even then, one may hope that in case of overheating and a subsequent BIOS event, hibernation outside of the operating system (i.e. BIOS hibernation) will work if the relevant BIOS setting is not "hibernation". Hopefully the OS will get an ACPI instruction to hibernate, but perhaps it doesn't work that way at all. Anybody out there who knows the details?

Using Win9x FDISK, I've assigned all space available to Win9x FDISK, and everytime the (hidden to Win9x/DOS FDISK) hibernation area turned out to start at cylinder 1017 (checked this with Linux fdisk later on). Add 64 MB RAM, 2 MB video mem and some BIOS data, round up to the nearest cylinder boundary and you'll end up at about cylinder 1026.
