Alain,

I've recently encountered the same issue, not sure if it's purely 
limited to booting from CD-ROM.
In my case I tend to use Syslinux --> Memdisk --> Disk Image ( --> 
bootsector --> kernel --> config.sys --> shell --> autoexec.bat --> 
commandline)

1) Does loading everything except UIDE work for you?
2) Does loading everything except UIDE work for you, if you later load 
UIDE from the commandline? DEVLOAD UIDE.SYS /D:CDROM
3) If you replace the XMGR/JEMM386/XMGR by Japhet's JEMMEX, does that 
work? ofcourse still load UIDE from config.sys
4) If you replace the XMGR/JEMM386/XMGR by Japhet's HIMEMX + JEMM386, 
does that work? ofcourse still load UIDE from config.sys
5) Does the same behaviour happen under MSDOS? Slightly more difficult 
question ofcourse, but FreeDOS kernel/shell occasionally is easy to 
hang/crash, SHELLHIGH is a culprit at times, for example.

I think JEMM is at 5.74 by now, can't hurt to use latest version I guess.

This should work:
DEVICE=A:\DOS\HIMEMX.EXE
DEVICE=A:\DOS\JEMM386.EXE I=TEST NOEMS
DEVICE=A:\DOS\UIDE.SYS /D:CDROM
DOS=HIGH,UMB
DOSDATA=UMB

Or:
DEVICE=A:\DOS\JEMMEX.EXE I=TEST NOEMS
DEVICE=A:\DOS\UIDE.SYS /D:CDROM
DOS=HIGH,UMB
DOSDATA=UMB
