I set the cylinder addressing to "Large" in order to better accomodate a planned dual-booting installation of DOS 6.22 and Win95. On boot-up to Win95, everything went fine (as expected) and the correct number of cylinders for the Large setting was reported by the BIOS. Now I get DOS 6.22 onto the machine and find the BIOS had its settings re-written to 1024 cylinders; I know DOS can only read 1024, but as to why it would write to the BIOS is a question- a mystery. I noted the same result after re-detecting the hard drive in the BIOS, setting it to Large and experimenting using Windows fdisk with the -x option.

You don't need to use the 'large' translation mode in order to use your HD. It's a trick intended for some *NIX versions that doesn't support more than 16 heads (LBA translation uses 255 heads), so you can use DOS (not Win95 in 32 bit mode) and *NIX together. You can use the LBA translation mode without problems, it's intended for DOS and Win95 works fine with it.
