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 88 of 122 | ANN.lu |
Posted by Mayonaise on 21-May-2003 21:56 GMT | For those that don't know; The 686B isn't a one off, alot of VIA's chipsets contain bugs, most of which result in DMA problems. VIA aren't completly stupid and reuse their designs, but it seems they don't fix the bugs in them first ;)
Problems are being blamed on the northbridge because this is where the problems *seem* to originate, the KT133 was blamed originally for many of the 686B problems until it happened in other boards and was then properly traced down to the poor 686B. |
