Hi, to bring in some thoughts from off-list... JEMMEX has a built-in HIMEM which apparently is known to have problems when memory useable for XMS is discontinuous, which happens quite often on modern (virtual) hardware.
The UMBPCI author tries hard to keep supporting modern chipsets which can be interesting if you do not need EMS. As mentioned, EMS is less popular than XMS anyway. To stay on the safe side, people should use HIMEMX + JEMM386 or other combinations instead of JEMMEX. Also, they should be able to understand the conflict potential of UMB and prepare to manually add X=... areas based on their personal insights. Having UMB areas conflicting with other things can cause hidden instabilities: The actual crash may be delayed until you touch the hardware or BIOS feature which resides in the conflict area while at the same time having relevant DOS data in the conflict UMB area at the same place. I would like to avoid discussions about specific drivers beyond the core "only use JEMMEX if you know what you are doing, make HIMEMX and JEMM386 the preferred option" recommendation and a warm mention of UMBPCI for those who have supported chipsets.
