"Clock not set"

[onlyonemac]

Hi!

As part of a project, I'm trying to find a way to work around the "clock not set" message when booting my Mac with no battery. My current solution is to write a small extension to set the clock to a more acceptable value (such as January 2013) before the box comes up.

The extension seems to set the clock correctly, but the box still comes up the first time. On subsequent reboots there's no box.

This indicates that either it's checking the clock before loading the extensions (but only showing the box afterwards), or it's using some other method for determining the "correctness" of the clock. How does it do that, by the way?

I also considered deleting the alert box resource, but I couldn't find it in either the System or the Finder files. And would that just cause a resource manager error message anyway?

In any case, I'm needing an answer quite urgently.

Thanks,

I think it checks the base value in ROM against the PRAM info, don't know when it does it in the boot sequence. It very likely does the comparison before the extensions load and then displays the box for input after the the Mac is setup for peripherals I/O, but it could be after.

Dunno, you said you needed a quick answer, so I took stab at it. ;D

Wouldn't it be easier to just put a battery in the thing?

I haven't got round to getting one yet.

Besides, that's not the point.
