[comp.sys.atari.st] NULLFILL vs FATSPEED

U46050@UICVM.BITNET (JOHN ZAFIRIS) (12/11/88)

Does anybody know why FATSPEED (the DFREE speedup utility) does not work with
the NULLFILL elimination utility proposed by someone on the NET some time ago.
I use NULLFILL in my AUTO folder to speed up my system by several orders of
magnitude but cannot use it with FATSPEED because it for some reason cancels
out NULLFILL.  Does FATSPEED use a VBL 'slot' like NULLFILL?  Does the version
I have possibly steal NULLFILL's VBL 'slot'?  Is there a version of FATSPEED
which does not?  (my version is in all probability an oooold one)

thanks in advance...                                        ...John
