I have an Asus P4SDX with Sis655 Chipset, 512MB RAM, GeForce2 MX400 video, HD's - WD80GB and WD60GB and I'm running Win98. My system has been running somewhat slow lately (even after Defrag) and it's confusing trying to figure out what might be causing the sluggishness. Asus advised me to enable DMA for my 2 HD's (Device Manager shows only my CD-RW's DMA enabled). SiS has a system check which advised I download the following driver updates: AGP (Gart) Driver v1.17E and IDE Driver v2.04. Since I'm not sure what these are for I'm a bit concerned about installing them. Can someone help me out and let me know if enabling DMA for the HD's and updating these drivers might help speed up my system. I want to make sure I don't do anything which ends up making it worse. Thanks in advance for any advice.
