After a total mishap and 98% recovery, I am now ready to try and upgrade the DOS on my PC. I am currently at AT&T MS-DOS 2.11. I have an AT&T 6300, 640KB memory, 20MB Seagate ST225 hard disk, 1 floppy, AT&T monochrome monitor. As I understand it, I cannot use SYS to upgrade DOS from 2.x to 3.x because 3.x is bigger. I must reformat. (Once I get to, say 3.1, I could then use SYS to go to 3.2 without formatting, right?) I have read quite a bit lately (here, in fact) that BACKUP/RESTORE between DOS versions doesn't work. Whether that's true or not (is it?), I am not planning on using DOS BACKUP and RESTORE. I got a copy of FastBack+, which I am told by others, works just fine on AT&Ts. Any comments? Will I be able to read FastBack+-written disks (under DOS 2.11) under DOS 3.x? Since I will have to reformat, what is the exact procedure? I think I know, but I would like to check it out before I start: 1. DOS BACKUP my FastBack+ directory, to RESTORE later onto 3.x disk, rather than reinstall it from scratch. 2. Low level format with interleave factor 3. 3. FDISK to create partition. 4. SYS to copy 3.x system. 5. DOS 3.x RESTORE of FastBack+ directory. 6. FastBack+ restore (all but DOS 2.11 stuff) Right?? Will I be able to run DOS 3.x RESTORE on DOS 2.11 BACKUP disks???? Next, I can go to either AT&T MS-DOS 3.1 or AT&T MS-DOS 3.2. Which should I use? Does it matter? I had heard that there was a problem under PC DOS 3.2 in reading 2.x disks? Is this the case? Is this the case with AT&T MS-DOS 3.2? What am I forgetting? Tell me. Thanks for the information.

Yes, so long as you used the same version of FASTBACK, the save/restore will go flawlessly (or so it always has been for me and everyone I know!). > Since I will have to reformat, what is the exact procedure?

I do not know, I have always just reinstalled FASTBACK -- a better alternative is just copy the \fastback directory to a floppy without using BACKUP/RESTORE (the only thing that is different from a reinstall is the presence of the backup directory file, I think). > Thanks for the information.

I tried it once, they changed the volume number storage from BCD to binary. I also tried that other program you mentioned, about a year ago. It did not work at all on my AT&T, something to do with the floppy, I am told. I gave it away to someone with a true blue, where it seemed to work well, if a bit frantically. Probably they have fixed this problem, I advise you to make very sure before buying. I use Intelligent Backup, by Sterling Software. |Since I will have to reformat, what is the exact procedure?

I reset it every few days, a minor aggravation compared with trying to get it fixed. The tell me I'm the only one with this problem, so maybe I'm doin' it wrong :-). I suppose if I were buying now, knowing what I know, I would buy 3.2, which, I hope, will either keep the correct time, or can be patched to do so (of of course, I don't know if any of this applies to your 6300, my problem is with the 6300+). |What am I forgetting?

There are a number of public domain programs that do that. AT&T's DOS has a new install program that replaces the older files with the new ones but I don't know about it working with DOS v2.11. Reformatting and re FDISKing the disk will allow you to use the smaller cluster size that'll give you a bit more free space on your 20 meg though. >I have read quite a bit lately (here, in fact) that BACKUP/RESTORE >between DOS versions doesn't work.

DOS BACKUP my FastBack+ directory, to RESTORE later onto 3.x > disk, rather than reinstall it from scratch I recommend just reinstalling the fastback plus directory or do what I did. I made a bootable version 3.x disk with fastback plus, fdisk and format on it and used that to format /S C: and to begin the restoration. > 2. Low level format with interleave factor 3. Your best interleave may be 4 or 6 instead of 3. I recommend getting a copy of Spintest to see what works best. My fastest interleave was 6 using the WD1002-wx1 Superbios Rom, 4 with the AT&T internal disk rom and now is 3 after using qfresh to tighten up my refresh time to memory. > 3.

There's an annoying bug in 3.2 that causes the clock to lose time. AT&T's just released DOS3.3. It's a little more money but it's probably worth being at the latest rev. I've never had problems reading different rev floppies with the AT&T dos versions. The 3.2 Dos clock fix is to get Biopatch 12 from some BBS. (I recommend the Right Choice BBS (201) 974-8317. Or the AT&T run support bbs systems -- (201) 769-5616,or 6397. >What am I forgetting? Tell me. You've got the right idea. DOS3.x is much better than 2.11. I re-low-leveled the disk and got 4mb more free space due to the smaller cluster size. -- Bill Pechter {sun!hoptoad,cmcl2!phri}!dasys1!pechter USnail 103 Governors Road, Lakewood, NJ 08701 AT&T 201-370-0709 Evenings

Numerous people on the network have complained about making Fastback backups without error, then were unable to read them onto the newly formatted disks. I wouldn't depend on it, though the most recent version may be reliable if you run in the slow (verify on) mode.

Certainly, caution should be taken if you plan to reformat your hard disk after you back it up (to ensure that your backup is good, etc). I admit, I didn't follow this rule (the first time), and I used the original FastBack, which may have been my downfall. However, on my second try I used FastBack Plus (with High DMA a.k.a fast and write verify on). I had no problems backing up or restoring. No doubt, FastBack Plus is a better program than FastBack (in my opinion :-). +--------------------------------------------------------------------+ | Mark H.

I would suggest you just write it to a floppy with COPY

This is really a matter of use. With an AT you can run as low as 2:1 and
get improved loading of programs which don't use mush CPU, such as
loading programs and reading files into (some) text editors. With
programs which do more CPU per byte read you will run faster with
interleaves as high as 6. You have picked a good compromise.
# 3. FDISK to create partition.
# 4. SYS to copy 3.x system.
Actually you want to FORMAT /S at this point
# 5. DOS 3.x RESTORE of FastBack+ directory.
Again, Id use COPY to avoid any possible problems.
# 6. FastBack+ restore (all but DOS 2.11 stuff)
I think that will work.
# Right?? Will I be able to run DOS 3.x RESTORE on DOS 2.11 BACKUP
# disks????
I wouldn't bet on it. Some people report problems. Why take a chance?
# Thanks for the information.
Hope it helps
