3]SYSINFO V1.93
3]By Nic Wilson
4]-------------
(JUMPDISK NOTE: Originally published in the September 1990 issue, this
program displays much interesting information about your system. It was well
received and since has been significantly updated.)
The program hunks have been written to use public memory so it will load
into fast RAM if available. The program requires about 100k of chip memory
and 36k of public memory to run.
3]SPEED COMPARISONS
The A500 STANDARD comparison is against a PAL A500 totally unexpanded,
that is, no Fast RAM. This program has a 3-bitplane screen open. This shows
how much the processor slows when running a program in chip memory while
having to contend with Agnus working overtime.
The B2000 EXTRA RAM comparison is against a PAL B2000 with SLOW RAM or
FAST RAM. The processor returns to normal speed even though the 3-bitplane
screen is open. This can show the difference in speed between slow RAM and
zero wait state memory boards. Our experience shows it only makes a
difference of around 0.01 or one hundredth.
The GVP A3001 comparison is against a B2000 with a GVP A3001 accelerator
card, with all caches and bursts on. The board also contained four megs of
32-bit wide ram.
The A2630 is not as yet accurate.
The A2620 comparison is against a standard A2500 with a A2620
card running at 16MHZ.
The A3000 16MHZ is not yet accurate.
The A3000 25MHZ comparison is against a standard A3000/25MHZ with two
megs of fast RAM 32 bit wide, and one Meg of CHIP.
3]FREE MEMORY
This shows the amount of free memory as if the program were not running,
so it is not accurate to the byte but is a very good indication of the free
pool.
The TOTAL MEMORY is the total amount of memory the Exec memory list
reports. Tests show this figure is around 800 odd bytes short of actual. This
is because the amount of memory Exec takes for itself never gets added to
this list.
RAM SPEED vs CHIP is a calculated performance test of CHIP RAM versus
PUBLIC RAM. The result is shown as a percentage increase in the speed of the
PUBLIC RAM. If no FAST or SLOW ram is available then the result will be
around 0%.
Any mounted devices the program does not recognize will be seen and
counted as a hard disk.
DH0: DRIVER IN shows the type of memory your hard disk device driver is
using. This is interesting, as it shows whether the hard drive is running at
its best. If is not in FAST, then get it in FAST, as it will operate faster.
2000/500 CLOCK only looks for the standard 2000 or 500 hardware clock. It
does not look for the multitude of different clocks that were available for
the 1000.
3]INTERNAL HARDWARE
This shows internal hadrware as the program has found it. ECS stands for
ENHANCED CHIP SET. If Agnus or Denise show this, then they are the lastest
custom chips. The number that is shown is the actual chip number. This helps
in identification of the chips.
Processors 68000, 68010, 68020, 68030 and 68040 are supported and will
be displayed if found.
Co-Processors 68881 and 68882 are supported and should be displayed
correctly, if my 68030 reference book is correct.
SPEED IN MHZ is a rough indication of the clock speed. This is not
accurate but is a good indication. It at least tells whether your system is
7MHZ, 16MHZ or 25MHZ etc. This is difficult to discover unless you take
apart the unit.
3]THINGS I WOULD LIKE TO ADD
1. Ability to check Amiga model. Is it possible?
2. Your ideas. Any suggestions --preferably in Assembler. I can
translate C if I have to, but it is such a pathetic language. Sorry, C
programmers but Assembler is so much nicer.
3]WHY
SYSINFO was written due to the lack of such a program on the Amiga. It
was written using HiSoft Devpac Assembler. I have placed this program on the
public domain so it can be used by everyone. I hereby give permission for
commercial publishers to distribute this program in any way they see fit, but
remember who wrote it with credits, please. There are no conditions, except
this doc file and the icons must accompany the program.
