Sounds right, or the other way around...
 
g=c250:5... That's sounds more correct... I never low-level formatted many MFM or RLL drives, just normal formatting those huge 20M 1 cubic foot drives that took an hour to spin up.
 
Drivparm, really? 3.5"ers? I've never had any issues accessing any 3.5 drives, nor 5.25 drives for that matter.
 
Ah... the extra math co-processor. You had the proc, but have it do math? oh, far too much work. No moath-co was an option up to the 486SX erra, wasn't it?
 
I loved those grainy games! Man, they were FAST on less than an average cell phone today. Though in some sprites, some assembly in certains places and let-her-go! AND They fit on 1 or 2 floppies! There just wasn't ANY overhead in there.... and I don't remember any bug fixes/patches every months like today's games.
 
5K nic driver? You don't like that the 100M driver also installs 300M of utilites, managers, registry changes, auto-loaders, balancers, notification utilites, and auto-updaters?
Man, I remember carrying around a single floppy that had multiple drivers, common files, a boot sector, telnet, and some misc. system utilites on it.
Fine. You're so smart you rig up the lights.

I saw drivparm on an apple in highschool, hense my comment about it. When I saw your response after mine I goggled it and it appears that it was on an apple to allow use of an IBM floppy drive, which I guess i didnt realize at the time.  I do remember the pascal teacher being excited she had 2MB on her Apple. I thoought she was an idiot because i had that on my commodore for a year+ when she got that on her crapple 2.  I was a commadork so you will have to forgive me for not realizing that one piece of inferior hardware was running another...  Tongue
I have to admit if you were typing that in dos you have me beat...  I came to Dos in 3.0 (or 3.2, that rings a bell too) and was mad because my 72MB ESDI hard drive had to be partitioned in to multiple drives until 3.3 came out. 

How many folks out there had a 287 co-processor?

g=c800:1 was used primarily to acces/launch the low-level format pgm for MFM, RLL and some SCSI drives. Most SCSI controllers used g=c250:5

Can't believe no one got the Drivparm - that particular command argument was used to get DOS to "see" 3.5" FDDs.

Desqview - allowed multitasking on pre-windows systems, while QEMM broke the 640K barrier and allowed expanded/extended memory to be interchangeable on the fly.

Sucks to be an apple user. I hope you grew out of that habit somewhere along the lines...

OPEN15,8,15,”N0:”DISKNAME,ID”:CLOSE 15

was the true mans (or kids) way to format a disk.

Deskview was an early gui if i remember right and qemm was a memory manager that was better than emm368.exe.  Heck I thought I ruled the world when I ran a commodore 128 BBS with 2.2Mb storage online including early multiplayer games.

Himem.sys, the first useful dos memory manager put small TSR code and other drivers like mouse.sys in to the space between the 640K and 1mb barrier.  Emm386 and later qemm allowed you to put those and other types of programs in to memory beyond the 1mb limit which enabled the use of memory hog software like NIC, CD-ROM and sound card drivers in DOS which ultimately allowed us to have "great" games full of crappy grainy video for years to come. Man, what I wouldn't do for a 5K NIC driver again.

I believe Expanded was the space between 640 and 1mb and extended was the space after 1mb if memory serves my correctly

Sorry, the geek in me is coming out...

(edited for spelling- I didnt fact check so I hope I got those right)

Quick - what was the difference between Extended Memory and Expanded Memory?

and the A20 gate?

Lets see....
DEBUG was a kind of break out of the OS, go into the BIOS type thing... Kinda like a STOP-A on a SUN.
-g=c800:1... I'm guessing low-level format. I remember doing soumething like that for the old SCSI1 drives.
driveparam's easy, that sets the drive parameters so that the OS knows what it's accessing.
 
Well, I have no idea what Desqview or QEMM86 is... I remember passing parameters to EMM386.EXE.

HIMEM.SYS started moving stuff out of the first 640k?, but you could get (and I had) a ... um... some sort of ghost that only used 1k and moved other drives like mouse, and Trident video drivers out of low mem, so that the hi-powered games that needed all 640k could run.

If I remember right, I had to buy a "memory manager program because DOS wouldn't recognize more than 640k
