Your new disk is not 40 GB. The 40 GB that is reported on the box or packaging 
that it came in is the number that the marketting department uses to make the 
disk look bigger than it actually is. By their calculations, 1 GB == 1 
billion bytes. But computers see 1 GB as 1024 MB, and 1 MB as 1024 kB, and 1 
kb as 1024 bytes. So if we take the number of bytes reported on the package 
for your new disk and convert it to real GB, we get:

40 * 1000 * 1000 * 1000 / (1024 * 1024 * 1024) = 37.25 GB

I don't quite understand this question. EVMS just uses malloc/calloc and free 
for dynamic memory management, just like almost all C programs in Linux.

Again, I'm not sure what you're asking. What do you mean by emulate? EVMS will 
do disk partitioning for you. Based on the above info, you have already 
assigned the DOS segment manager to the disk (or else it came that way). So 
now you simply need to create segments (i.e. partitions) using the freespace. 
Using evmsgui or evmsn, you can select that freespace segment in the 
"Segments" panel, and choose "Create segment" from the pop-up menu, and then 
enter your choices for the various options.
