I noticed similar difficulty on a friend's 486.
Anybody else notice similar behavior, or know how to fix it?
Thanks for any help,

I have the exact same problem. Didn't have it on version .99.... I was
able to play it through to the end with my Gravis Gamepad just great
(I also have a 486DX2-66), but once I upgraded to v1.0 it started doing
that. There may be a bug in the 1.0 upgrade... I tried playing it with
the various Dos extenders, but no luck.....

If you have enough memory, like 16meg or more, load RAMDRIVE.SYS
in your CONFIG.SYS file with the options:
device=c:\dos\ramdrive.sys 12288 512 1024
Reboot your computer, and tada, you have a 12 meg disk in memory.
Switch to that drive, it should be labeled something like:
MS-RAMDRIVE. Copy DOOM onto that drive, but beware, because everything
you copy will be erased once you shut the power off, now run DOOM.
It is really fast!!! (loading and stuff)
Have fun, be careful, and always play Ultra-Violence!!

Hopefully Chris means a software cache. A hardware cache
is a far less intelligent solution. With the money
you spend on a disk cache you could buy more ram and
configure as you like.

Well, personally *I* kind of *LIKE* my hardware cache. I have an EISA
32-bit caching IDE controller, and (a) it's blindingly fast, (b) I don't
have to burn conventional memory on loading software caches, (c) cache
conflicts are a thing of the past, and (d) I have one cache that works
for both DOS and Linux.

Some points here.
If youve got a 4 Meg machine would you upgrade to
8 Megs or get a 4 Meg cache controller (c.c)?
With 8 Megs you can choose to give 1,2,4,6 Megs for a cache
as you like - and this cache is fast (RAM to RAM). With a
4 Meg c.c you run at EISA speed, and are stuck at that size.
With Linux, you use the full 8 Megs for the system, it uses
a sophisticated *dynamic* cache allocation scheme - grows and
shrinks - as needed. It doesnt know of the 4 Megs on a c.c,
and therefore wastes memory using its sophisticated *dynamic*
cache allocation scheme. Much the same is true for Windows.
DOS may seem faster, but Ill bet a good EISA controller (no
cache) with a software cache of 4 Megs and another 4 Megs
of RAM is as "blindingly fast" as a 4 Meg c.c on a 4 Meg machine.
My analogy : A car (machine) with a trailer (controller).
You could improve performance by putting an engine in the
trailer - or getting a bigger engine for the car. Which
would you do?
Which I'll answer here this time, but if it goes any further we really
should move the discussion to a more appropriate group.
] If youve got a 4 Meg machine would you upgrade to
] 8 Megs or get a 4 Meg cache controller (c.c)?
In that situation, the obvious choice is to upgrade main memory to 8Mb.
4Mb is really inadeuate for any serious use. However, I'm not in that
situation; I have 16Mb of main memory plus my 4Mb caching controller.
Your mileage may vary, obviously.
] With 8 Megs you can choose to give 1,2,4,6 Megs for a cache
] as you like - and this cache is fast (RAM to RAM). With a
] 4 Meg c.c you run at EISA speed, and are stuck at that size.
With a software cache, you can transfer data from system RAM to system
RAM, using the system CPU's time, at system bus speed. With an EISA
caching controller, you transfer data from controller RAM to system RAM
at EISA burst-mode speed, up to 33Mb/sec, using the comtroller's CPU
time. My experience, having tried both, and having tested both with
four different speed testing utilities plus real-world usage, is that
the caching controller is significantly faster and *LOTS* more reliable.
And incidentally, if I only had 8Mb, I'd never burn 6Mb of it on cache.
With only 8Mb, RAM is too precious to burn more than 2Mb on cache.

The same is *not* true for Windows at all. Windows doesn't *do* any
caching of its own. That's why it insists on loading SmartDrive (even
if you're already using another, better, software cache).
Meanwhile, Linux's own cache can write to controller cache instead of
directly to disk - looking like about a hundred times faster disk, to
Linux - even if you *don't* install the controller's Unix drivers.

Well, if we're going to get picky enough at speed comparisons that we're
going to worry about the difference between EISA bus speed and main memory
bus speed, let me point out that my caching controller (like most others)
is a bus-mastering device with its own processor (in this case, an 80186),
and is quite happy to go off and perform disk and cache management tasks
in the background while the CPU is busy working on other things. With a
software cache, the CPU has to take time out to manage the cache. As stated
above, my observation - from real world experience, backed up by testing
utilities - is that the caching controller *is* faster. Plus, it's one
extra device driver and/or TSR I don't have to load - and cache software
can be a real memory hog. The biggest value to me of the caching controller
over, say, SmartDrive 4.0 (when running DOS), is that I get back almost
40k of conventional memory, *even loading Smartdrive high*.
] My analogy : A car (machine) with a trailer (controller).
] You could improve performance by putting an engine in the

] would you do?
Poor analogy. Here's a better one:
You have a library with an attendant at the front desk, who checks books
in and out *AND* restocks the shelves. You want to improve service at
the library. Do you:
(a) Tell the front-desk attendant to work harder, or
(b) hire an assistant to re-shelve returned books?
: ] If youve got a 4 Meg machine would you upgrade to
: ] 8 Megs or get a 4 Meg cache controller (c.c)?
My example was (perhaps) for the more typical user, with
the standard 4 megs, having Windows etc.
: With a software cache, you can transfer data from system RAM to system
: RAM, using the system CPU's time, at system bus speed. With an EISA
: caching controller, you transfer data from controller RAM to system RAM
: at EISA burst-mode speed, up to 33Mb/sec, using the comtroller's CPU
: time. My experience, having tried both, and having tested both with
: four different speed testing utilities plus real-world usage, is that
: the caching controller is significantly faster and *LOTS* more reliable.
As above, most folks dont have EISA, and disk activity is
important - VLB doesnt have burst mode (PCI does), and most machines
are ISA/VLB - the processor time to disk time is far less important.
For ISA this is very important. did I make a point here!?
Getting back to DOOM - on my 8 Meg machine, with 4 Meg SMARTDRV cache
(only for DOOM), I never see disk activity once it has been on for a
while - the same would be true of a 4 Meg controller. But I can cut
this down to 2 Megs when doing some work. A more typical situation
perhaps.
: And incidentally, if I only had 8Mb, I'd never burn 6Mb of it on cache.
: With only 8Mb, RAM is too precious to burn more than 2Mb on cache.
Neither would I, just pointing out flexability.

What happens when this kind of system needs to grow and shrink?
Ok, Ill have to admit that Alaric is winning this on most counts.
But I want the last word (in this group at least :) - The final
blow...
Cached controllers are better because they have a seperate processor
to do the work - not just because they have RAM on them. Ideally,
one would have a co-processor for disk management which can 'chat'
with the main processor about how much memory it needs (using
the main system RAM) and release it as required. This sounds like
what Alaric mentioned with Linux - more or less. For the DOS
and Windows user who wants a good price/performance improvement
with DISK and other things - get more RAM and use soft cacheing.
If you run DISK intensive stuff - get a cached controller.

I just feel that this thread is a prime example of ANAL netters.
Of *course* the man meant a software cache. This is almost too obvious
to dispute. Yet we have to waste another good 10 posts to discern this.
Yeah, yeah, I realize I started it, and admit it, but I can only take so
much before I just have to be mean.
Whatever...continue with the thread...flame me at LEAST another five times,
so we make par.
:) :) :) <--- Happy faces. Don't get your feelings hurt by this post.
Ciao, baby..
Of *course* he meant a software cache. Working at that level
will help no-one. Someone posted about using a RAM disk. The
software cache solution was easier - someone posted it - but
if you thought RAM disks were the answer then maybe your
knowledge is limited and requires some considerable clarification.
Im glad of my ANAL abilities - are you?
