I tried activating DMA mode on my Win98 machine for my SATA Drive. But as soon as i reboot, everything is very slow.

I use a SATA Disk with an IDE to SATA Adapter on Primary IDE and have a Intel i815 Chipset with 82801BA (ICH2) controller with the Intel Chipset Drivers 3.20.1008 installed.
On Secondary IDE I have a IDE to CF Adapter as master and a DVD Drive as slave if I only activate DMA for this two devices everything works fine.

Any chance I can activate it for the SATA Disk too or should i just give up?

Any info on the SATA-IDE adapter? Does it use a Marvell chip or JMicron chip on it, or something else?
There is absolutely no excuse for these to have a compatibility issue with an i815 chipset, but it is what it is. You could try the opposite brand as that helps sometimes.
