Jemm

About Jemm

Jemm is an Expanded Memory Manager for DOS, based on the source of FreeDOS EMM386. It comes in 2 versions: Jemm386, which requires an XMM (HimemX, for example) being loaded first, and JemmEx, which already has the XMM included.
 
Jemm has several advantages compared to FreeDOS and/or MS-DOS EMM386:
  • needs only 128 bytes (upper) DOS memory (Jemm386)
  • needs very little extended memory
  • is faster
  • works with MS-DOS, FreeDOS and DR-DOS
  • will use features implemented on later CPUs to further increase speed
  • unlike FreeDOS Emm386 Jemm has full VDS support
  • both Jemm386 and JemmEx can be loaded and unloaded from the command line
  • with its FASTBOOT option one can shorten the reboot time to just a few seconds
  • offers a 32-bit protected-mode API and allows to install plug-ins (JLMs [Jemm Loadable Module])
