 Not totally, though. First of all, both types are real physical
 memory.  The difference is in how the CPU addresses it. 
 Extended memory refers to memory above 1 M address space, as you 
 correctly noted. But to access it the CPU *must* be switched into
 protected mode.
 
 Expanded memory (also known as LIM -Lotus,Intel, Microsoft) was
 developed in order to overcome 8088 address space limitations.
 Some hardware maps 4 16 kb pages of 16 (I don't remember the exact
 number) Mb physical memory into 8088 address space. Mapping is done
 through 4 8 bits I/O registers. Later LIM was extended to address more
 memory.

 As far as 80386 expanded memory is concerned, a software driver does
 the job. CPU gets switched to protected mode and a chunk of memory 
 is moved into 8088 address space (1M). 

 Actually some 386 moms supported hardware LIM.

 You see, memories don't suck. It is Bill Gates who sucked his
 biliards developing such a wonderful DOS.

 I would do it for the wider array of controllers especially SCSI disk 
 controllers. The beauty IS that you can slam in an old AT card or 
 next-years new "hotter than I could have imagined" video-capture card ?

 I would expect to be runnning  MS Windows NT in a year and the 16 Megabyte 
 DMA limit of AT would be somewhat restrictive.

 By the way, EVERY article I have read has concluded that, given windows and 
 an accelerated Graphics Card (S3, Mach-8), the local bus cards are NOT 
 appreciably faster (~10-15%) than an  equivalent AT-based card. So the 
 question could be "Why Local Bus?"

I need some help.  I bought a 40 meg Maxtor IDE drive of my friends and 
there exited two partions on it.  So I did what I did with my last drive
when I only wanted 1 partition was to delete all the current partitions.
Know when I use dos 5.0 fdisk and try to produce a primary partition 
it works for 2 minutes and then says that there is no room for partition.
I imagine know that I have to get some other software to create a dos partition
on this drive.  What did I do wrong and how can I correct.  Does the drive
need formated again.  I know you are not suppose to do a low level format 
on a IDE but is a dos format on a hard drive considered a low level format. 
Right know I can't you a dos format because I get a "Invalid Drive Type" and 
when I try to boot on this drive I get a Invalid Partition.

The plus has dram, the pro has vram.  I gather that the main difference 
will be that the plus will be a little slower than the pro, and won't support
quite as good refresh rates.

24bit color at 800x600,  64k color at 1024.

ATI said that they would be released wiith os/2 2.0 drivers.
The cards won't be available for another week or two.

The best route when you are not satisfied is to talk to the manager of
customer service to get the "straight and narrow". I would recommend that you
contact the manager of customer service at Oxy You can send a fax to
612-486-0019. Bring it to the attention of the Manager of Customer Service.
Please include an order number and a telephone number that you can be reached
at with the times that you can be reached at with the fax.

If you don't get a reply back from the manager, I will see what I can
do to contact him/her. 

ZEOS and Occidental are seperate companies run by seperate managment.

Message forwarded to the manager at Occidental.

Don't blame it on Oxy... it's basically the same at all companies
which practice "overbooking."  I'm not saying that they are
doing this, but it is possible.  It could also be possible
that they have a few bugs to work out of their order
department... including training sales people who use to work
at Micky D's. 

To get the cash flowing, some smaller and medium sized companies 
will lead you on to believe that the system will ship the next day.
It's bad for business in the long-run (no repeat customers on
the stalled orders), but in the short-run the profits are
good.

   I also have a 386-40 motherboard using the FOREX chipset.  Seems that
alot of 386-40's use this.  I know mine does because it is the FOREX 486
chipset due to the upgradability of my motherboard.  I don't remember where
I read it, but I have read that the FOREX chipset is actually faster than 
many others due to the fact that it is integrated into fewer chips than 
most.  Don't know if it is true or not, but Norton SI gives me a higher
rating than my friend's 386-40 which uses Chips & Technology's chipset.

   Most local bus systems I have seen have the Video and IDE controller
on the same 32 bit local bus card.  The ones I have seen also seem to
have an additional 16 bit local bus slot.  The new VESA boards have
more than one slot as well.
  Another thing to keep in mind in this debate is the algorithm used
in software caches.  I read somewhere that there is no difference
in speed between a hardware and a software cache.  Even on EISA.
Even on a multitasking environment.  One of the reasons given is
that the software caches use better algorithms to find and store
the data.  I don't think they tested this on a local bus system
though (I don't even know if there are any local bus caching
controllers yet).

The ZIF Socket technology originated in mainframes. The ZIF socket that

Quite right that the math processor isn't there in the i486SX part,
but I understand that Intel has actually remasked this chip to a
smaller feature size and no longer uses DX parts without the FP unit
connected. 

It is also true that a 486SX ought to be faster than a 386DX at the
same speed, but for the same money he could get a much faster 386-ish
part.  Personally, if I didn't need the floating point, I would buy
the AMD 40 MHz 386 part.  I wouldn't buy a 486SX part on a BET.  This
thing was invented as pure marketing cruft to try to undercut the fast
386 clones while maintaining higher prices on i486DX parts.  Buy a
clone or buy a real DX part.
