Installed on Secondary IDE Sony DRU 510A DVD Writer seems successful, but it will only play audio CD's & Video CD's, not DVD's!. I have also managed to write a DVD successfully with the supplied software - SONIC MyDVD,which will play on my DVD ROM which remains as a slave on the Primary IDE with the Hard drive. Without the latter I would not have been able even to load the supplied Sonic software! I tried a limited installation of only Hard Drive Primary, & DVD Writer Secondary, but nothing changed! DMA is enabled, but the current Transfer Mode shown is not the same for all devices. How do I change it if neccessary? Help?
Thanks for the response huggyg71. Motherboard is ASUS A7A266 with Ali chipset, BIOS version 1008. ASUS website offers no clues as to necessary updates? (and updating it scares me!) The only problem is that the new DVD Drive will not read any kind of DVD ROM! I have also tried another SONY DVD Drive with the same result. Any other ideas.
a cdrw/dvd combo i had was only working in "pio mode" and i could not enable dma not matter what i tried.this was causing problems like you describe ie/not playing dvds and causing hangs when discs were inserted.
updated my motherboard drivers,straight away udma mode 4 available and all discs worked great,no hangs anymore.
Thanks for the response Huggyg71. The board is A7A266. Could you be more precise on what you term Motherboard drivers. If you mean a BIOS update,I have read the warning in my manual to update only if you are sure it will resolve the problem. None of the later BIOS updates refer to anything other than later AMD CPU support, so am reluctant to go there if not sure!
