Yes, after I formatted the drive, I installed DOS and copied the I386 folder as well as SMARTDRV.EXE into it. DOS boots fine from the desktop without any problems and if I wanted I could just get started installing Windows but that would be on the wrong system. Unfortunately, I'm stuck with a "Missing Operating System" error every time I stick it in the laptop. I'm starting to think there is something wrong with the way the laptop bios checks the hard drive. That laptop bios is the version A12 and the newest version is A13. The only difference is in some battery charging algorithm.
