Try only to realise the truth : Comment 237 of 335 | ANN.lu |
Posted by Nate Downes on 06-Jul-2004 10:42 GMT | In reply to Comment 226 (Chris Hodges): You know, this is the best explination I've seen in awhile.
I might add that the reason why the AmigaOS required this "software-flag" for the classic hardware is that the classic hardware had no concept of a northbridge, there was no mannerism for DMA transfer included with any hardware back in that day, so the Hi Torro guys made their own. But times have changed, there is now a hardware-flag for PCI DMA transfers.
Ironically, it is the fact that AmigaOS's core has not had an update since 1994 that allows it to work in such an environment. |
