I'm currently using windows 98 and I was told to install my IDE drivers since I didn't do it when I formated my computer. So I found out what my motherboard was and installed the driver for it but It didn't speed up my harddrive, cd rom, etc. and now my Imation 48x24x48 CD-RW burner stops at 20% and gets an error (SCSI/ATAPI Command Timeout Error) Note: I'm using nero 5.5. So I then uninstalled my IDE driver hoping that It would work again but windows then Said that I had a SiS 5510 Motherboard (Which I really have a SiS 660 (I Think!)) so I installed it but it still had the same error and the speed hadn't changed but now I don't know how to get rid of this driver since I didn't install it using it's installer. Also someone told me that turning DMA on could fix it. If that is true how can I do it. Also if you can tell me how to uninstall the current driver. And anything else that I should know so that I can fix it.

Thanks in advance.
