The hard drive version of TI v11 on my system is unstable but the CD version works just fine. As my boot manager (BootUS) creates a new MBR that can't be configured to work with TI's F11 feature (F11 never shows at boot time), I'm wondering how to get the CD version of TI installed on an empty primary partition. This would allow booting into this trimmed down version of TI like to a separate OS. Once all the files listed below are copied from the recovery CD to the empty primary partition: bootmenu.exe bootwiz.sys f11.cfg kernel.dat mouse.com ramdisk.dat splash.run it seems to be just a matter of writing the boot sector with some command like: sys c: c: /bootonly You could boot form eg. FreeDOS CD to get the command line working. Any ideas are appreciated.
