Hi all ATers, this is my 1st post, don't know whether this is the rite place to ask this....but here it is
I was looking at my old 486 one day, it has a HDD controller as a add on ISA card. Info in win95 device manager showed that it is not DMA capable (no DMA checkbox), at the same time there are both 8 and 16 bit system DMA channel available.
I thought to use slave DMA, special hardware are not necessary but only an IRQ, a DRQ, and a driver that will set it all up, therefore it would be possible that such a driver can increase performance and use system resource more efficiently. However I could not find anything about such drivers for windows. Does that mean my understanding is not quite complete and this idea is actually not feasible? Can anyone shed some light on this.......
I know it is a bit late to ask this, it should be ask when the mighty 486s were still roaring on the planet
