Upgrading the BIOS was the solution in that case. interesting. i have cycled through all the different bios options, but it is always the same 1.2 GHz. i recently upgraded to the latest bios, so i probably will have to wait to try a new bios. meanwhile, the laptop is going back to ibm anyway because of its overheating problem and the broken second ram slot. i will tell them to check out the cpu/bios as well. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

What is wrong here? To other IBM T30 users: Is your CPU identification correct? What's wrong here is that the BIOS/ACPI firmware in your laptop runs your CPU at a reduced rate in order to make the battery last longer. Manufactureres have taken great care to not make it clear that the specs they give you are all reachable, _just_not_at_the_same_time_. You may be able to twiddle things in the BIOS or using ACPI and get faster CPU but less battery lifetime. It can also be that the case that the cooling solution (ie: fans, fins etc) does not work well enough and the ACPI code has slowed down the CPU in order to not melt anything [*]. In particular our ACPI code does not seem to always start fans when they should due to high temperatures.

I have not had any issue running a buildworld on my T30 on a hot day. (It hit 105 at my house yesterday and 103 at Lawrence Livermore about 3 miles away.) It runs at 1.8 GHz and takes under an hour to build CURRENT, about 35% longer than it took with STABLE. No 11s sighted. It does get HOT..too hot to really be a laptop unless you have well insulated pants, but within spec for temperature. (At least with ACPI running so that I can monitor the temperature.) The exhaust vent is blowing a strong stream of very warm air. I do see messages that the system is switching between performance and economy mode when I switch from AC to battery, but the CPU pays no attention and the speed stays unchanged under both APM and ACPI. :-( It sounds like something is very wrong with your T30. -- R.
