Crash Test: DMA Problems with VIA's 686B Southbridge 2/4
Version 1.3 April 12, 2001. Translated into English by Naily.
Testing by Oneself?
No Problem! If you want to check for the error at home, take care of the following:
The IDE Stress Tool (usage at your own risk!)
Microsoft Visual Studio 6.0 Service Pack 5 (test file, 130 MB)
For double-checking we used two motherboards with VIA's KT133 chipset and the old 686A southbridge. On the Epox 8KTA-3+ Windows 2000 wouldn't even boot any more. Replacing the board with the "old" Epox 8KTA+ resulted in 250 flawless test runs without any changes in the system! I can only recommend that you be on alert as far as the behavior of your IDE devices is concerned.
Next: 3. Diary of a Fiasco
- Windows 98SE, ME, and 2000 come into question.
- A Soundblaster Live greatly increases the probability and frequency of the error.
- You need to copy files from IDE1 to IDE2 and vice versa.
- The IDE devices should run in (U)DMA mode.
- No error messages will pop up. You need to check the data integrity of the files.
- On our system, the error mostly occured after 7 - 15 GB, sometimes, however, after 200 - 300 MB already.
