Hi, finally I've completely finished my multitasking and scheduler code.
It works fast, supports V8086 mode tasks and ring changes.
Now, for ATA, can I do a new DMA read while other is working? I couldn't find anything about it in Busmaster DMA documentation. (Documentation is:
http://www.osdever.net/downloads/docs/idems100.zip)
Or should I wait a transfer to complete, then start a new one? In other words can I do more than two transfers same time / one is not completed yet? Or should I only do one transfer at a time, and wait transfer to finish with a semaphore, mutex, etc.
If I can do more than two transfers same time, should I do anything special? Is running it as usual enough?
Thanks in advance
