Thx for explanation. I don't have any idea why they put some reserved memory holes there. I would understand if it is for ACPI or other MMIO devices but they are usually allocated near the top of 4GB.

I think that SBemu use EMS (not sure but it requires EMM386) so all 32MB of EMS can fit to low 512MB. But depends how memory holes will be assigned on other PCs. Anyway SBemu no longer works for me so I don't care...
Maybe you could add an option to JEMM to enable scan through all available blocks (would be off by default) and manage them...
