don't bother with Windows 95, it's not going to install on Dosbox 0.65. There was once a special patch for the source code that let me eventually install it, but that pathc is no longer up to date and won'T work with current source code. Save yourself the pain.
All I did to make the 2 GB image work was to enter the correct values (as the bochs image tool gave me) and then mount the image. mount a dos 6.22 floppy image, boot from the floppy, fdisk, choose all availlable space, "reboot", (same mounting and booting as before) format c: /u
