REGISTER MEMORY requires that the amount of memory to be registered
is stated in hexadecimal format. If you are adding an amount of memory that
is not in the preceding table, then you need to calculate the amount.
Calculating the Amount of Memory
The following figure illustrates how to calculate the amount of memory you
are adding:
1. Start with the amount of memory you are adding stated in decimal MB.
Obtain this number from the documentation that came with the memory
you are adding.
2. Convert the memory value from MB to bytes.
NOTE: A megabyte of memory is more than a million bytes. One megabyte equals
1,048,576 bytes in decimal.
3. Convert the number of bytes from decimal to hexadecimal notation.
To do this calculation, you can either use a calculator that converts
decimal numbers to hexadecimal, or you can convert manually.
For example, 1 megabyte = 1,048,576d, which is the same as 100000h.
So 1,048,576 bytes in decimal equals 100000 in hexadecimal.
To convert manually, consult a specialized manual.
256 MB 16 MB = 1000000h 240 MB = F000000h
400 MB 16 MB = 1000000h 384 MB = 18000000h
1 GB (1000 MB) 16 MB = 1000000h 984 MB = 3D800000h
3 GB (3000 MB) 16 MB = 1000000h 2984 MB = BA800000h
3 GB (3000 MB) 64 MB = 4000000h 2936 MB = B7800000h
