Changing splash screen on Palm OS 4.1?

[bhtooefr]

I'm going to assume it's possible... and, I'm going to assume that this isn't device-specific, otherwise, please move this to the Fossil forum. (I figured this wouldn't get much visibility in there...)

Anyway, I'd like to change one of the splash screens (preferably the device manufacturer screen, but the Palm Powered screen would work, as would adding a third splash screen) on my PDA. Is this possible? And, how would I do it? I take it it'll take a ROM reflash to do it...

[dmitrygr]

no need for rom reflash and yes, possible
but why?

[bhtooefr]

Eh, I just want to. :)

I was doing some googling, and the only thing I came up with is IDPalm, which won't quite do what I want to do, and crashes on this device anyway.

Is there a procedure for this? I couldn't find it from searching the forum.

[dmitrygr]

yes
write a simple app
that will draw a fill-screen picture when it gets launch code 5
it will be your third bootscreen

if you want it to stay onscreen for X seconds, add a call to
SysTaskDelay(X*100);

In fact, your modification with PowerDrive allows for a customized splash screen (and progress bar). REALLY COOL!

After it finishes than the Palm Powered splash screen takes it's place.

I wonder if PowerDrive could be the splash screen for the whole boot process with the progress bar too?

Looks like PowerDrive is for the LifeDrive, this is running a SLIGHTLY older OS. (4.1.2, no NVFS, no hard drive, etc., etc.)

Looks like I'll have to study Palm OS programming a bit, so I can write an app to do that...
