I was using kernel 2036. Just tried 2038 -- no effective difference. The JEMM
error is different now (Error 06 at a seemingly random CS:EIP, near the top of
conventional memory but where there is no associated PSP).

are installed in a UMB ad other times not, depending on the exact
circumstances. E.g., if UMB's are available and the CPU is in real mode, I

Maybe not..? The issue does not appear to be related to JEMM (as usual).

Hi Bret,

(Rugxulo's bare DOS disk, with a 2008-03-08 kernel, build 2038) and it
