dma problems

By dlippus ·
my stepfather just purchased an amdk6-2,500mhz chipset with a Tyan S1590s Trinity AT100 motherboard slapped it together with a creative labs cd rom and a samsung hard drive. Did an upgrade install from win95 to win98.He now has a problem with the dma,where as it is non-functional (cd-rom and hard drive now slow up the pc.)He did mention having to work around a cab file, but im not certain that it had any baring on the dma.

Go to Control Panel, system, and delete the entry for the CDRom and HD.
Reboot and allow 98 to detect and re-install those drivers.
That usually works for me.

Good Luck!

Open the System properties in the Control Panel. On the Performance tab check to see if any of the drives are in MSDOS compatability mode. If so restart the computer and, just before you see the Windows 98 splash screen, press the F5 function key. Press the Esc key to clear the splash screen and verify a line referencing 'HIMEM.SYS is testing memory'. If this line is not there press Ctrl+Alt+Del and try the F5 key again. Repeat until successful. This will boot Windows into Safe Mode. Select 'OK' at Safe Mode prompt. Open the System properties in the Control Panel. On the Device Manager tab find the main hard drive controller and remove it. Also, check for redundant device and remove both copies of all duplicates. If, for example, there aretwo 'Floppy Controllers' delete both of them. Make sure you have drivers for non-standard items. If this doesn't fix the MSDOS compatibilty problem, locate the hard drive controller drivers for that motherboard and install them.

Hope this helps. Good luck.

I believe #2 is on the right track - you should cleanup multiple devices while in safe mode and allow Win98 to re-find the devices. Also, did you have to setup any ISA or legacy devices in the BIOS and manually reserve and IRQ or DMA resources? Ifthe reboot after safe-mode clean-up doesn't do it, investigate the DMA resource use in device manager or msinfo/msinfo32. Best of luck.

Not clear on the question, but will offer an easy resolution to potential problem. If the HDD used any disk management boot software (like EZ-Drive, Ontrack Disk-Manager, etc.) because it was in a PC that couldn't handle a large drive (BIOS restriction, say), then the management utility must be removed from HDD boot sector. If HDD is new or never used large drive disk management, then this is not a solution. Good luck.

I also like #2's answer. Before doing any removals of devices though, make sure you've copied the WIN98 cab file directory to the C drive, as you may not have access to the CD drive during the reinstallation of the removed devices and most genericdrivers can be found in those files. You can copy them from the WIN98 upgrade CD using Windows Explorer while you're in safe mode. Good luck!
