This routine will run standard memory tests on your
memory. The options are:
-F Test Fast memory
-S Test System Chip memory
-L Long memory test enabled
-V Verbose messages
-D Debug messages
-A all memory tests performed(except Long)
-B values test
-E sum address test
Chip memory will be tested first if requested then Fast memory
Memory will be allocated using the standard system allocation
routines. What ever memory is left when this program runs will
be tested. A linked list of memory is made for both Chip and
Fast memory.
The Long test will run faster on very fragmented memory(small
blocks) but will be more effective on unfragmented memory.
The values tests on each block will be:
a) zero/non zero byte
b) alternating bit test
c) walking byte test( if -L selected )
The sum test on each block will be:
a) fill memory with a value which is the two halfs of the address
plus a pass count(four passes are done).
b) check each location for changes, must have the computed value.
If an error occurs the address and data are displayed. This program
will take ***ALL*** available memory for it's test.
Source for this program is available by sending a couple of dollars
and a disk to the above address. Support Shareware!!
