In
/bootopts, usebuf=20(for 20 buffers in main memory) to override number of compiled-in EXT/L2 buffers. Replaces olderbufs=option which specified both EXT and XMS buffers.Use
xmsbuf=2000(for 2000 buffers in XMS memory) to override number of compiled-in XMS buffers. Settingxmsbuf=0will disable XMS and use EXT/L2 buffers. The new maximum XMS buffers is 2975.With the recent enhancements to the buffer system, ELKS will now run with as few as 10 EXT buffers, for low memory systems.
Next step is dynamically allocating the L1 cache buffers using
cache=.
