I have a 65 MB Mitsubishi RLL disk for use in my Compaq Portable
and have gotten tired of having two drives (C and D). What I'd like is
formatting software to partition the drive into one large 65MB partition.
Also, I'd like the accompanying device driver to be small (the smaller the
better). I don't have any expanded memory or any fancy boards, just an 8088
(actually a NEC V20) based Compaq. I've been using the drive for 3 months
as two drives and it's behaved perfectly. If anybody knows of any public
domain or inexpensive ( < $35 ) products to do the job I'd be appreciative.
NOTE: I specifically DO NOT want to upgrade to DOS 4.xx! It's to buggy
and DOS 3.3 is smaller.
Thanks,

Compaq DOS 3.31 allows partitions greater than 32 Mb.

IBM PC DOS 4.01 allows larger than 32 Mbyte partitions, so does Zenith DOS 3.31
and DR DOS. DR DOS is probably the most generic and portable of the versions
that do.

Nec DOS 3.31 also allows partitions larger than 32mb. One question though, how is this done? I remember reading in PCMag that instead of formating at 16 (something) it does it in 32 (something) /f $************$**************$************************************************$ *_____/\_____* /francis * bitnet : francis@cunixc.bitnet /////////////* * / \ * DVX Corp * internet : francis@cunixF.cc.columbia.edu * * /<()>\ * Alpha Sys * UUCP : ...!rutgers!columbia!cunixc!francis * * /______\ * Columbia Center for Computing Activities (CUCCA)........ * $************$**************$************************************************$ --I just want to be me so I speak for myself.

Besler compaq 3.31 does also, but i think it uses 32 bit FATs as opposed to 16 bits like the rest of the world. some packages that allow >32mb parts use >512byte sectors (very inneficient). i'm not sure how Disk Manager does it, but the primary partition can still only be 32. the extended, however can be as large as you like. best bet with DM is to use a 1 MB primary, and a large extended, so you don't blow away your root. i don't like Disk Manager becaause it requires a device driver, and my customers usually blow away the driver, or the device= line in their config.sys i use 4.01 DOS.. question: many people complain about 4.01 having problems, but the only problem i ever saw was with a cheap shareware program. what are these supposed incompatibilities? tim .

I came across a couple of patches on SIMTEL for DOS 4.01. I applied them, but I'm not sure what they did (I should look a little closer at them). Something about buffer handling. I also saw in the documentation for Lantastic that they recommend 3.3 over 4.01 for network use.

This is not the case actually. All the 3.31s use 16-bit FATs, just like you would expect. The thing they change is the sectors per cluster size in order to make the big disk fit. This is not efficient, but it works. DOS 4.0 uses the same strategy, but allows up to 2GB (3.31 is limited to a wimpy 512MB, which HAS been reached by the 615MB drives). It does this by raising the sectors per cluster size. For a 2GB partition, that would mean 64spc, or 32KB clusters! And, since a cluster is the REAL minimum size for a file, that little 10 byte batch file actually takes 32KB from your disk (but then again, if you've got 2GB, would you notice?). This can be a problem. I was once told of a man who had filled his 10MB drive and went out and bought a new 20MB to replace it. Well, he backed up the 10MB drive and restored it to the 20MB. Much to his surprise, he only had 5MB free! Was his disk bad? No, the sectors per cluster size had doubled, and with a lot of small files this resulted in a lot of unused space being taken up by the small files. > i use 4.01 DOS.. Good man. I use it too, but I have to say I just did it out of the habbit of upgrading... But what did I get? DOS 4.0 has a better command line interpreter, DOSHELL (better known as DOS HELL), a new command called MEM (interesting really, the neatest thing I've seen in DOS in a while), and the ability to put a little more in extended memory (not much though). > > question: many people complain about 4.01 having problems, but the only > problem i ever saw was with a cheap shareware program. what are these > supposed incompatibilities? > Well, I don't know if any incompatibilities, besides the ones that come up because somebody hard-coded the line that says: if (_dos_major_ver != 3) then throw_up(); I do know that DOS 4.0 takes a LOT more base memory than 3.31. That is why some network companies recommend it, because with thier drivers and DOS 4.0 there isn't enough memory left to run any apps. Oh yeah, I just remember that LapLink 3 says it won't work with DOS 4, but then again it doesn't understand 16-bit fats (ie. it wont work with big 3.31 partitions either). +==========================================================================+ | Scott Shaffer | Compaq Computer Corporation @ Houston TX | | Systems Engr | (These opinions do not necessarily reflect those of my| | SW Development | employer, friends or any living person.) | +==========================================================================+ "Unix is a registered bell of AT&T trademark laboratories." from a University of Utah Research Paper

It is the device driver that allows you to access the drives and printer on one (slave) PC as local devices on another (master) PC which is *NOT* compatible with DOS 4.01.
