Execbase & Memorychain

Legionary · 27 October 2016, 20:46

Kan someong give me a hint on how to remove fakefast in the memorychain so it dissapear? In other Word shut it of.

I made my own solution by allocating all available fast and try to take ass much fgast as possible. This "so called" no fast works in most cases but not all, therefore i need expertice help.

All those utility boots must remove it from the memorychain, but how? Can some one post a link on execs all functions (i've forgotten alot)

"Move.l $4.w,a6" (A Classic line)

Note sure if this still is interesting to you but anyway, I'd simply patch Exec's AllocMem/AvailMem routines (using SetFunction) to disable any fast mem. AllocMem would simply always set the MEMB_CHIP and clear the MEMB_FAST bit, AvailMem just needs to set the MEMB_CHIP bit.

An excellent source on Amiga programming stuff is http://amigadev.elowar.com/. You can find the includes & autodocs (which contain all Exec functions among with everything else) there.

You are almost there.
I think you need to patch AvailMem() and AllocMem() and set the MEMF_CHIP flag (maybe clear MEMF_FAST also?)

p.s. You are familiar with the "NoFastMem" tool in the System folder right?

Which is exactly what I already wrote!

Personnally this is where i would start, even if it's just by disassembling it.
