JFS Boot Block :: Bochs Adventure

Wikis > JFS Boot Block :: Bochs Adventure

So, getting a MBR and os2boot on a hard drive image was a real pain. None of the current CDs would boot to a point where I could get the job done. I resorted to doing it the hard way. I mounted an old 630 meg IDE hard drive (just having this around should label me a packrat) and booted the system with an eCS 2.0 RC4 CDROM. Using the eCS tools I made a compatible partition which was bootable and wrote the MBR. Next, I did a long JFS format on the partition which completed but with errors toward the end of the format process.
