Alas, it doesn't matter how big the request is.
OK, obviously I am still missing something here from when I got the driver booting again. Presumably something with current_nr_sectors, vs nr_sectors, maybe? I thought it was odd that all the transfers were exactly 2 blocks. I'll go ahead and take this one. I will also go ahead and check to see how much data the hardware can transfer at once as well, but I expect it is quite a bit. I am still working on getting a
group of folks to test patch #5 to see if it works as well. Anyone with appropriate hardware willing to test can contact me. All I have access to is my thinkpad 700 PS/2, and a 50Z that is a 286.
