Via admit 686b bug well nearly
June 18, 2001
To whom it may concern:
During the past few weeks, problems were reported on several web sites stating that one of VIA’s chipset has compatibility issue with Creative SoundBlaster Live PCI Sound card. After debugging, verifying, and checking compatibility between our VT82C686B and other devices, we concluded that the problem is not totally related to our chipset. We found that the system problem will happen only under certain configurations and certain procedures, and only occur under Athlon processor based systems with VT82C686B chipset and Creative SB Live card. We also checked whether our chipset has any compatibility issues in other configurations, and the result was we did not find any such compatibility issues.
The configuration is described as follows: One IDE HDD ATA-100 or one ATA-66 HDD and enable default DMA mode; one IDE DVD-ROM and enable fault DMA mode; one Creative SB Live PCI sound card; one VGA card; and copy file, W2KSP2.exe (Win2K service pack2).
Consequently, we also developed a new IDE driver to resolve the compatibility issue with the Creative SoundBlaster sound card, and this IDE driver will be posted at our website for users who have Athlon based systems using this configuration.
Best regards,
VIA Technologies, Inc.
Nicely forgetting that it also occurs with other soundcards and also in machines without soundcards, Zip drives that don't work properly Cdrw etc. It looks more like it's something wrong with the ata 100 implimentation. The 686a has a lot less problems.
