From a news-item at VGR.com it appears that the current Articia-northbridges might still have DMA-related problems:
"Mr. S.W. who sends over screen shots of newer AmigaOne 800mhz G4 hardware, has sent over 2 screen shots of the new A1 with G4 running 'amigaone xe/g4 7451 800mhz, excalibur radeon 9000 pro 64mb ddr ram, valueram kvr133x72rc3/256 kingston'. He wants to know '.. if other aone users have that problem as well..', 'it never outputs the same checksum with dma enabled when testing an iso file which is larger than the swap space used'
You can see the Radeon 9000 Pro screen shots here: DMA On & DMA Off."

Articia: Still DMA-problems? : Comment 13 of 122 | ANN.lu |
Posted by Joe Pillow on 20-May-2003 12:17 GMT | In reply to Comment 12 (Olegil): "Why can't it be the actual chip that handles DMA transfers, namely the VIA southbridge."
Because the very same problem happened on non-April PEGASOS mainboards, but doesn't on PEGASOS boards with an April fix. Keeping this in mind, it is likely that ArticiaS *is* the problem. However, I don't expect you or anybody else who is strongly involved in the AmigaOne project, to admit this.
It definetely would be interesting to see whether ordinary users of the A1XE have the same problem on *their* machine or not. The current information was posted by an anonymous person afterall. |
