I have an elderly Toshiba Satellite 4200 laptop which ran Win98 but could be switched to a DOS Cad program. I now want to upgrade it to XP Home yet retain the Dos program, but I read that XP won't run Dos programs. Would it work if I set up XP on the laptop and DOS on an external USB HD (or vice versa to avoid any USB startup software) such that if I started up the laptop with the HD connected, the external HD would take startup preference and load IT'S platform? Or is there a better way ....?
Your other alternative would be to dual boot the system with both XP & Dos installed, (best in separate partitions for each OS. A good boot loader is that included in Acronis Director suite, but there are others.
Thanks all - I am going to try Virtual PC 2004 as a first attempt, and failing that then a dual boot loader (which is new to me but I am happy to look into it). BTW, my Toshiba has a 512Mb RAM installed; speed is actually not a problem.
