Hi There, I need some technical help again. I've tried to upgrade my dos version on my IBM AT 286 clone. I have a MS-Dos 3.3 currently and I got an IBM Dos 4.01 from a friend. I had problem to upgrade since these two dos have some difference. But I don't want to spend more than $120 to buy a MS-dos 4.0. Is there any way to upgrade a Ms-dos with an IBm Dos without re-formatting my hard drive first? I like the dos 4.01 very much but just hesitate to rebuild my hard drive. Any suggestions are more than welcome. Thanks in avance. Matthew Huang
