I have yet another question regarding XT's and AT's. I don't understand very much about access hard disks (ESDI etc). I would like to get the max throughput to my hard disk. I thought that it would be best for me to talk directly to the controller but companies like Ultrastore/Rancho/etc said that this info is not available. They said that I would have to go through the bios (i guess int 13h). Do I have to use the BIOS for max throughput? Are all BIOSes created equal (ie. is the bios call for a ESDI disk the same as the bios call for a IDE or MFM ect)? Also, is it possible for me to format my hard disk with a specified number of sectors per tract (say 16 instead of 17)? Thanks, Dave Rajnauth
