I use win98, and I am learning assembly language....but nothing appears to reveal the main thing.....why floopy disks still use pooling mechanism to get formatted inside windows? Is there a way
to control its DMA or IRQ that could let formatting in the background smoother?

Old drive controllers use to have its own settings that cannot be optimized anymore .... in the past years, windows 3.1 used pooling with 100% dedicative mode, that is.... rather than choppy process handling, the entire system lock up until finishing formatting task.

I use GRDUW to format 1.72 disks. I love this program but it´s an example of a poor ´pooling´ mechanism.

Let´ discuss it.... thanks!
