Jim, 	
	
1. What was it about Windows 95a that limited it to 2.1 Gig aprox? Then
Windows
95b raises it up to 8.? Gig. How come? What changed?	
The original Win-95 used FAT-16 (the Windows 3.1/3.11 disk format, hence
the size limit.  When Win95 first came out, hard drives were only in the
600-800Mb range, so it wasn't a problem for the "upgraders".  Within
about a year, drives breached the 2Gb size, but by that time the OEMs
were all using OSR2, with native FAT-32.
	
2. Why am I told that Windows 98SE will not support a hard drive that is
over 30
Gig?	
It will, but performance suffers as the FAT table gets larger.
	
What are the 'real facts and real issues?  	
	
	
Thank you.

All of the following answers relating to hard drive
size are dependent upon having a BIOS that can support
the larger drives, regardless of the operating system
used.

1) In theory, Win 95b can address a hard drive that is
2 terabytes (2,199,023,255,552) in size. The FAT32
table does not scale well in that as its size
increases, it takes more time for Windows to find
information in it. It also takes more time to
calculate free space at boot-up. The maximum size of
the FAT32 table is about 128 megabytes. The maximum
size of any one file on a FAT32 drive is 4 gigabytes.

2) Yes, you can have a 10 GB hard drive in Windows 95b
on a laptop.

3) Yes, you can run an 80 GB hard drive under Windows
98.

4) Many, people sell computers without an installed
operating system.  eBay is an excellent source of
these systems, as are most local computer stores (NOT
a chain store, but a privately owned store.)

5) No operating system requires a particular brand of
BIOS.  Some operating systems may work better with
certain versions of a BIOS, particularly when you have
an operating system that contains advanced features
relating to hardware.

6) BIOS is the Basic Input Output System that allows
the computer to boot before the operating system is
loaded.  This allows the system to boot, perform the
POST (Power On Self Test) which tests the basic system components to
make sure that they are functioning.

CMOS stands for Complimentary Metal Oxide
Semiconductor.  CMOS is a type of chip that is
frequently used to store the BIOS code.  They are
frequently used interchangeably, but they are not the
same.

7) I have never suffered a hard drive failure either. 
The data on hard drive failures does not indicate that
one type of use is necessarily harder on a hard drive
than another.  The major cause of hard drive failures
seems to be excessive heat, caused by inadequate
cooling of the system that the hard drives are
installed in.

Education is when you read the fine print. Experience is what you get if
you don't.

Wilderness itself is the basis of all our civilization. I wonder if we
have enough reverence for life to concede to wilderness the right to
live on?

Great occasions do not make heroes or cowards; they simply unveil them
to the eyes. Silently and imperceptibly, as we wake or sleep, we grow
strong or we grow weak, and at last some crisis shows us what we have
become.
