Screen resolution way too small to see.

Does anybody have any ideas about changing the screen resolution prior to booting ? I’m using the Risc OS on a Raspberry Pie 1 and the display is so small I can’t read or decipher what anything is. Any help to my resolving this dilemma would be greatly appreciated.

As far as I am aware, which could be way out of date….
The only way to set that mode is forcing the modes using the GPU in config.txt
Take a look at this
I think that may force the mode you end up getting in the end.
Not really sure why you would want to read that anyway, it goes pretty fast.
It’s been awhile since I used a Pi, so RISC OS may now allow you to change modes “properly” – whatever properly means!

The CONFIG.TXT file.

I use the following to force 1280×1024 (but note, the GPU will forever stay in 1280×1024; so set this no less than the native size of your display):

hdmi_drive=2
hdmi_group=3
hdmi_mode=36

I believe what you’re after is:

*UNPLUG BootFX
*CONFIGURE WimpMode 28

You need to unplug BootFX as it doesn’t handle lower resolutions during the boot sequence.

Be aware that when you upgrade the ROM image, you must *RMREINIT BootFX before swapping the ROM over…then *UNPLUG it again once the new ROM build has booted. This is because the Module numbers sometimes change between builds, resulting in a machine that may not boot.

I have had this problem too – Here is A solution.

first – get the configuration IN RISCOS correct for your needs.
then find the configure file – in !Boot.choices.boot.predesk.Configure

It will be an obey file SIMILAR to this – Monitor

Set the ‘access’ to ‘Protected’ to prevent the problem recurring
if the wrongsettings are in the next version of the ROM.

Save a copy (or two) renamed as ‘Screen’ in a suitable BackUp directory and PIN that copy to the Pinboard – in the lower left quadrant and
SAVE THE PINBOARD !

If you find the screen is too fine to read, just click on this file.

LoadModeFile BootResources:Configure.Monitors.Other.Generic WimpMode X1024 Y768 C16M F60

Mmm normally that is on two lines:
LoadModeFile BootResources:Configure.Monitors.Other.Generic
#WimpMode X1024 Y768 C16M F60

Does it work on one line?

Always select textile mangling things as the first option. You will rarely be wrong.
