I'm trying this in a VM now.
I was able to get to the Prime95 menu by typing /opt/mprime/mprime27
and from there I could select the options (which stress test, how many CPUs...).
Now I'm trying to create a custom P95 entry that would show in "User-defined" in UBCD.
I added this to the custom.cfg:
MENU LABEL Prime95
Your help message goes here.
COM32 linux.c32 /ubcd/boot/cpustress/bzImage
APPEND noapic ubcdcmd=mprime27
P95 seems to just start running, I suppose in default mode which is blend.
I'd like it to either start with my predefined settings ("In-place large FFTs", all cores, not submitting results) or to ask me (as if typed /opt/mprime/mprime27).
Is this possible and what do I need to add to the custom.cfg file?
I found out this page
and the key is using -ubcdargs
, so the last line should beAPPEND noapic ubcdcmd=mprime27 ubcdargs='-m'
and it will bring up the setup dialog.
Now I'm off to actually using this and see how it goes. I wonder if the eventual errors are displayed like in the Windows GUI... would be nice if they were logged somewhere too.
Tried this on a real machine (i5-750) and got a whole lot of kernel panics and errors before even getting to the actual stress test.
Sometimes it would work, but mostly not.
