Hi all. The past monday I installed the DOS7.10, in a 6.4Gb Samsung HD(I was using 6.22 in those machines)
I have the followings trobles:
a) I can´t make a floppy boot. When I make sys a: and reboots, the command.com apppears like if it was corrupted. at the prompt, the 486 asks for the command.com
b) I could´t do that the OS recognices the second partiton (Whit the fdisk.com I make a boot partition of 2047Mb and the rest in another. The first has no problem, but second neither format can do to it.
c) System sometimes crashs loading the killer.sys. What does it do?
d) Norton Commander Version 5.0 doesn´t work. I can open the NC, but since it, I can´t "call" other programs, like mpxplay.exe, text editors, nor games.Does anybody know what happen whit DOS 7.10
Pd: all programs were very used by years whit 6.22, then programs are not the trouble
Thanks.

a] Did you get an eror from sys a: ?
b] Did you format the second partition?
c] As far as I know, killer.sys is not part of DOS. So what DOES it do?

If at first you don't succeed, you're about average.

Hi M2
If the Bios accepts it you can have multiple 2G partitions. If you stick with real DOS or Win3.x apps that should be adequate filespace.

For Mechanix2Go:
a) No, in fact, I format this floppy whit this SO,and after it sys it. And I tryed whit a second floppy in case that the first was failed, but the final was the same.
b)the DOS7.10 don´t want that I format it.He told me that I can´t format a network device(¿?) And, I haven´t network card
c)It appears in a line in autoexec.bat. I dont forget any info of it (note: may be that in the firt message, I putted killer.sys, but actually I don´t remember the exact extension of that file)Ánd, my interest of 7.10 are the following:
1) Long filenames.
2) I currently I have a 40Gb hard disk with Ontack disk manager, partitioned in 20 2Gb units that are full of MP3 and OGG´s But 40Gb HD are now difficult to buy and (in Argentina) a 40Gb costs 65 U$S and 120GB in 80U$S, but device letters are only 23 in 6.22
3) I don´t want to migrate to Windows because I hate it.(Can you undestand me? :-)

Hi,
I'm not sure about where in this process you are.
Get a good, solid boot floppy of the same version.
Disable the line in config.sys which is causing errors.
M2
If at first you don't succeed, you're about average.

Long filenames are not a function of "DOS 7.10" - those are provided by the freeware LFN tools bundled into the installation.
It's 'just' Windows DOS that's been patched for compatability with Win31, plus some freeware tools all rolled up into a package.
The only real feature of value is the ability to use FAT32
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.

B) The 'can't format network drive' will occur if you attempt to format the cdrom. If that error occurred when attempting to format the second partition then I'd think you've created an extended partition but no logical drive within it. As such dos doesn't give it a drive letter and the cdrom will have the next available drive letter.

DAVEINCAPS,
I think you're exactly tight.
M2
If at first you don't succeed, you're about average.

Ok, boys. I beliebe that you are right. It is very possible that I forgot to make this step in the fdisk.exe.
Very thanks. During the following weekend I will try to restart all from the very begin. I found a couple diskette makers, and I will try to install from diskette. If it is well done, in another disk will try again with CD. But, first step I believe is to do in the easy way.
Thanks, boys, the monday I´ll tell you what happened. My 486 will be very happy to use 120GB HD´s!!!!:-)

I just thought I'd mention that killer came
with my copy of DOS 7.1, and was
installed without asking. If anyone figures
out what it does, I too would be interested
to know ;)

antique,
Another case which points out the adventures waiting when you get involved with a non-standard DOS.
Can be very good, but requires much effort.

"My 486 will be very happy to use 120GB HD´s!!!!:-)"
Wouldn't that be nice?
Installing a different DOS is not going to change the BIOS HDD limitations on a 486
KILLER.EXE - Abort to dos on invalid opcodes. (less freezing)
... make of that what you willOnly two things are infinite, the universe and human stupidity, and I'm not sure about the former.

Hi all. I´m very happy. DOS 7.10 is working, but like always happen, not at the first time. I try 5 or 6 times so I can find the troble. The apparently inocent Norton Commander was generating all problems. When I use it from another disk, there is nothing abnormal, but when copy it to C:/, in the following boot process, files becomes corruped or not loaded, or hangs up during satrt up. I know that in the other HD´s I have virus, (never I had trouble whit them), but may be the responsible of the fails. Or the limitation to 8.3 chars? I don know, but until sunday 6 PM it was workin properly. I must learn to use the dosshell.exe to replace nc.exe, or look for a non viruses version.
Ah, jboy, I know the 8 Gb limitation of the 486 BIOS, by this cause I found in internet OnTrack Disk manager that overcomes this limitation. Actually, I am using 40 Gb in that biggest machine!!!. Ah, the motherboard has been "tuned", like cars!!!! Thank all!!! :-))

My personal experiences would lead me to recommend getting that Norton crap off your computer.
The bios limitation was you're talking about was a 1024 cylinder limitation. This gave a maximum cylinders/head/sectors setting of 1023/16/63 or a little over 500 meg. A few later 486 bios' exceeded that limitation and a few of the earlier pentium I were still affected. But in general with the advent of the pentium motherboard, bios' could handle up to at least 8 gig.

Yes, Dave, this is my case. I have 5 pc´s 486 in different configurations, and whit the same µPC (AMD 486)in UMC Version 1.7 (2 machines, not PCI), 1 UMC V3.1,3.2, 3,3, and 3.7, with 120 mhz, with PCI slot (overclocked, still in W95), and all them has the 8 gb limitation. But, OnTack Disk Manager and Western Digital Disk managers, both can overcome this limit. Repeating, I actually using all this 486 with 40 GB Westen Digital (in true, are 41.1GB) with DOS 6.22, but partitioned into 20 2Gb units C/u. But, in a previous message, I told that the cost beetween a 40 and a 80Gb disk is minimun, and 40 Gb are only used. But, the letters of drive are only 23, and to have the half of disk unused is wrong. By this reazon, I want to migrate to 7.10
And, DO NOT WANT TO GO WINDOWS NOR PENTIUM!!!
:-))

That's fine (different strokes... whatever) - I'm just not sure how successful you'll be with the 120Gb drive you mentioned on that relic.
Dosshell has some issues under "DOS7" - due to changes in command.com (iirc) you can't shell out to DOS or launch executables from dosshell - which is a drag - otherwise it works ok unless you have too many files (10,000+ I think) and then 'out of memory' errors etc.
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.

I did´t know that limit. Well, but I believe that this limit is much greather than the files I will storage in the 120GB, because I fill it with long MP3 and OGG files, all them are electronic music with a media of a 1h 20 min, and some themes of 3 and up to seven hours of playing (Yes, I dowload from some Hungary pages a theme of seven hours or 427 Mb!)So, in 2Gb I putted about 15 themes or 24 to 25 hours in all. So, in 120 GB I may save about 1000 MP3 or OGG files, well under this limit you mentioned. Ah, in DOS, I use MPXPLAY V 1.48 for play them.
Thanks, Osvaldo from Banfield, Buenos Aires, Argentina.

Yes, well, that's fine - you will definitely benefit from FAT32 allowing partitions > 2Gb, that goes without saying.
120Gb on a 486? Overlay (of course) but even then, I'm not so sure..

XP: Since about 6 or 7 years I am using this 486, I know them, I also know his limitations, but I promise, and I am sure, that 486 will work fine with 120 Gb disk.
I also promise to send you notices when I but the disks, and install all 7.10, programs and music. Ah, now I am thinking to put an FM brodcasting with such amount of music.!!!! And, why not, a .com internet radio?

Well, good luck, hope it all works as planned
(btw, it's jboy - not 'XP')

That´s Ok. Sorry jboy by the rename.
Another question: Is there any program that replaces the desactivated defrag.exe ( I use it once a mouth, but yesterday at the dos command prompt, told me that defrag has been desactivated because of preservation of long file names)
Thanks again.
