View Full Version : Booting old Dos's via Flash drive on a P4

May 18th, 2014, 01:13 AM
I recently started playing around with an old 2 gig flash drive, I flipped the RMB and windows XP sees it as a fixed disk, I set up Dos 6.22 on the flash drive with a couple of extra partitions and booted my HP P4 desktop and it booted into Dos no problems, i can access the extra partitions in Dos and XP just fine. I was quite surprised at how well my USB Floppy drive worked as when i use it in Windows XP it can be a bit hit and miss as to whether it reads / writes a floppy or not but in Dos it worked fine on all the discs i tried to read.

I wiped the Flash drive and setup Dos 3.3 which seems to work fine too, I haven't done any other testing yet.

With my HP having a nice clear 17" screen it's so much easier on my eyes, I'll try installing some old software later.

Anyone here running old software via flash drive on newer hardware ?.

I keep a "rescue" system around on flash pen drive with DOS and a few utilties . Also a couple of live Linux distros.

Very handy when you need them.

Yes very handy indeed, My main problem is lack of space even though i have gotten rid of 90% of my collection, It's amazing how fast that free space got filled up with new bits of furniture :-( At least the ear bashings are not so frequent any more. I mainly wanted to use a few old dos programs and this has worked out very well so far.

I use my copy of MS-DOS 6.22 at work for some PC repair functions. Works great, I've run that on something as new as a XEON or Core I7.

Craziest thing I did to see backwards compatibility though was the time I put the black 360K Floppy drive in my Pentium-D dual-core box and played Microsoft Adventure and ran DOS on it off old floppies....I wish I still remembered how I pulled a nifty trick though where I managed to "reboot" DOS over itself....ie. something I did with a DOS command re-initiated MS-DOS's boot sequence (STARTING MS-DOS_) without having to go through POST again.
