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

Thanks in avance. > I have 'upgraded' from MS-DOS 3.3 to IBM DOS 4.0 by simply using the SYS command to transfer the system to the hard drive. HOWEVER, this will not re-partition the hard drive, so you're still stuck with a partition that is 32MB or less. It is my opinion that the largest or perhaps the only reasons to switch to DOS 4.0 are: 1.) Have disk partitions greater than 32 MB. -or- 2.) Software compatibility. If YOUR reason is #1, then your going to have to re-format your hard disk ANYWAY. When you consider that DOS 4.0 takes up more of your base (640k) memory than previous relesses, your may want to stay with DOS 3.3. I know many people who prefer 3.3 for that very reason. But if you need Big disks and 4.0, bite the bullet and repartition.

Although I have not checked IBM's PC-DOS 4.01 specifically, I know that MS-DOS 4.01 can be installed _without_ reformatting the hard disk--a nice and most welcome touch. (Just the same, backup your entire hard disk before updating your system. I love computers, but I trust 'em as far as I can throw 'em.) (Note: I work for Microsoft, but I do not speak for Microsoft.
