Recently I had to have the hard disk on my machine. When the technician replaced the disk, he formatted it and installed DOS 3.3 as per my request. However, instead of installing MS-DOS 3.3 (which is what I own, have the floppies for, etc.) he installed IBM PC-DOS. I didn't notice this till I had lots of stuff on the disk. Two questions: 1. Does this matter? (My machine is not an IBM, by the way.) 2. Can I "fix" this by simply copying IO.SYS and MSDOS.SYS from my DOS floppies? I'd like to avoid having to reformat the hard disk to install the correct version of DOS if possible. Jim Mann Stratus Computer jmann@es.stratus.com

Using the DOS copy command will not work for IO.SYS and MSDOS.SYS must be in certain sectors of the drive. Copy COMMAND.COM onto your drive from floppy. You may have to replace the DOS support files (XCOPY,FORMAT etc) with the ones from MS-DOS but I don't think so. Hope this helps. -Walden

Yes, since you've most likely violated a licensing agreement. 2. Yes. Remove the readonly/system/hidden attributes from the IBM files, delete them, then sys c: using the MS-DOS disk in drive a:

The only difference you will notice is that SYS and FORMAT /S will no longer work properly if it's PC-DOS's IBMBIO and IBMDOS, and MS-DOS's utilities (or vice versa). > 2.

Of course, if you can do that, you can also just rename IBMBIO and IBMDOS; but be aware of the not in item 1. You *should* be able to delete IBMBIO.COM and IBMDOS.COM and then SYS the system (after having booted from the floppy, and using the SYS command from the floppy, not from the hard disk.). If SYS refuses, reboot the system from the floppy after you delete the files, then COPY both IO.SYS and MSDOS.SYS to the hard disk. (You reboot to make sure that DOS will put them in the lowest available clusters. -- _ Kevin D.

Unhide IBMBIO.COM and IBMDOS.COM and rename them to IO.SYS and MSDOS.SYS respectively.The order is important!!! Copy the MS DOS 3.3 files over the top of the renamed files and all should be OK.I think you could even do SYS C: for that matter. Jack Lupic Scarborough,Ontario-CANADA

Copying the 3.3 files (io.sys and msdos.sys) isn't quite enough as the bootstrap loader on the first sector of the partition tries to load ibmbio.com and ibmdos.com the next time you reboot your computer. SYS C: will take care of that, though. What comes to the original question, I haven't encountered any problems running IBM PC-DOS 3.3 in a variety of clones over the last couple of years. I haven't ever bothered to compare whose manufacturer's dos gives the biggest tpa but there shouldn't be a big difference. Of course it is wiser to use the dos you received with your pc as it may contain some added value features like support for dos 4 partitions etc. >Jack Lupic Jari Artes
