I probed this setting on another older Pentuim system (RH6.2, kernel
2.2.17) :
- no special setting : 560 kB/s
- "delay=0" setting : 725 kB/s
Performance increased about 30%. This is wonderful !!

Sorry, but this is misunderstanding. I have single epat chip with
single IDE channel. Usually I have on this channel only single IDE
disk connected. Sometimes I need connect on it secondary IDE disk (as
slave). I use mentioned params and all is OK - both disk are
accesible.
But sometimes I run linux from this external HDD (on it is root
filesystem) - booting from floppy, epat + pd support build-in into
kernel. In this case I cannot access on seconadry IDE disk - it is
not detected during kernel booting. I thing that some params can
resolve this problem.
Thanks to all for answers and help.
