shsucdx is probaly your cd-rom driver right (loaded in the config sys). You need a driver and mscdex as well. I thought mscdex was on one of the dos 6 floppies but didn't install by defualt. I seem to remember manauly extracting it once.
But yea, why use dos. to play mps's load up a small distro and use mpg123. I have the "A" set of slack installed on a 128M CF card booting up to mpg123 for my truck PC.

technically you can't turn it off if you have any programs running because those programs could corrupt something. I've never seen a dos system corrupt anything just sitting at the dos prompt though mostly because it doesn't have 500 files open like windows.

I run slackware and edited the script where the partition is mounted r/w so the drive ir running read only so nothing can mess it up.

I took the mscdex driver and dosemu wouldn't even start. :|
This is annoying

you didn't try to replace shsucdx with mscdex did you? the cd-rom driver should be loaded in the config.sys and mscdex should be in autoexec.bat. You need both.

yea, install slackware or the more minimalistic vector linux, and mount the root partition in read only and mount a /mp3 partition in read/wr mode (and mabee a /tmp and /var in read/write, although that could be done through symbolic linking with folders in the r/rw "/mp3" partition)

that aught to take care of things for ya. and through triming down the /etc/rc.d/ directory you can make the bootup much faster. to make it even faster you could compile a mostly module less kernel that doesnt have suport for stuf you dont need (ie: firewire, scsi)

I replaced them. Copied from the archives:

AUTOEXEC.BAT had
LH /L:1,15472 C:\DOSUTIL\SHSUCDX /D:MSCD001 /V
and CONFIG.SYS had
DEVICEHIGH /L:2,28816 =C:\DOSUTIL\GSCDROM.SYS /D:MSCD001 /V

That was plain DOS with memmaker, though, not dosemu. Not sure if that was the pair of files that even worked. (I had problems with shsucdx). No idea if it applies and it'd have to be modified of course, but for what it's worth...

Whitehat wondered:
Why in the world are you using DOS for anything?

Cuz it's neat. And I don't need to swat a fly with a nuke. Linux has these ultra-high-powered and ultra-complex databases with the whole server/client thing going on and, on the other hand, my scripting's not good enugh to fake something minimally workable. I just run an old DOS db in dosemu. It's actually nice to have a tiny simple system if it's up to a given task and you don't need anything more. Why drive an SUV to the mailbox, y'know? Just walk.

But my 486 is on the ropes and I don't know how long the 586 has got, so it's dosemu. My db doesn't know what a CD is, though, so I never tried to make the CD work.

you can setup windows so that you can "just shut it off", i dont know about XP tho
turn off the caching write requests or what not

did i hear someone mention DRDOS??? i used to use it BW (before windows)...i thought M$ bought digital research at one point and trashed it...back in the 80's i was a dos programmer..and a novell reseller...i loved DR-DOS..am gonna google it....but is this the same product?

"i loved DR-DOS..am gonna google it....but is this the same product?"

Novell bought DR-DOS and renamed it Novell DOS. I bought Novell DOS 7 and ran it for about 5 years, well into the era when Windows prevailed. When Novell gave up on DOS they sold the rights for DR-DOS to Caldera:

http://www.caldera.com/company/drdos.html

Caldera sued Microsoft over DR-DOS:

http://www.joewein.de/dri.html

"Caldera then filed a lawsuit against Microsoft over its anti-competitive
practices against DRI. Caldera's lawyers and their witness documented ample
evidence of the anti-competitive practices and dirty tricks that Microsoft had
used to drive its competitor out of the market. At the beginning of 2000 the
lawsuit was settled out of court in return for Microsoft paying a reported
US$150-200 million to Caldera."

As far as I know that was the end of DR-DOS.

So the ultimate version of DR-DOS is Novell DOS 7. I still have a copy on a bootable floppy. It is handly when I forget and power down with a CD in the CD-RW. I boot up with the DOS floppy as the easiest way to untangle my computer's insistence on booting the CD.

Thanks Steve

gonna keep those links....i've got to find my old copy..know mine is pre-novell.... i'll be commenting again soon.... thanks for the info...

geez...DR-DOS...brings back memories of how things might have been if M$ did't buy up and/or ruin every innovative OS on the market....

Linux is my new OS....
Hey Bill....u can't buy Linux can u??? LMAO

Thanks again Steve

Tom

Hey Steve

Thanks for forwarding the article....it's interesting how it's now incorporatiing linux into it's features...it may not be open source, it may be expensive...but i also think it's worth a look...

Thanks again
Tom

p.s. found my old dr-dos 6.0 disks...thinking about setting up an old computer and seeing if the disks will still do an install....culater

speaking of shutting off the power err.. "just hitting the switch" how could you configure a linux system to do be able to do that?
no disk caching?
anything else?

You would have to umount all of your hard drive partitions. Each partition has a record which says whether the partition is currently mounted or not. At boot when you try to mount a partition the kernel will ask you to run fsck if the partition does not show that it was sucessfully umounted.

When you umount a partition part of the umount is to write all the dirty cache buffers. Another way to write the dirty buffers is to issue a sync command. See:
man sync
man umount

Steve Stites

but then you have no mounted disks...
i mean how do you keep the kernel from holding disk write buffers to begin with?
like in windows you would turn off"disk caching" or something like that
