Some configuratons of CONFIG.SYS with QEMM makes UMBs visible for QDK LOADHI.COM and MFT but not for DOS (MEM, HILOAD etc). At result, then that is impossible some with QDK LOADHI high-loaded programs (e.g. Norton Commander) to normally unload (interrupts restore, but memory not releases). If UMBs are visible for DOS utilities they can become invisible after starting of WFW 3.11 with MS network drivers (and not restore after exit Windows). To prevent this effect, CONFIG.SYS for some reason must have a line HISTORY=ON,... But why? 2. I found a serios conflict between NWCache (all updates of NW7 and OD7.01) and Norton Commander 4.0. If DPMS not loaded and NWcache loaded then a trying to set at one panel of NC a floppy disk and at the another Info (^L) causes non-normal NC behavior and system crash. I found this interacton between NC 4.0 and all these NWcache also under MS-DOS 6.22 but never under DRDOS 6.0. I think, this "compability with MS-DOS" is not useful!!! 3. QEMM cannot optimize OD 7.01 (release conv. memory) equal good as NW7. CONFIG.SYS created with QDK OPTIMIZE under NW7 may work under OD7.01 but free memory is less. Therefore a best solution for today is Novell update 15 on OpenDOS and copying OPENDOS.INI to NWDOS.INI. But why? 4. Some full-screen DOS utilities work not normally without /N switch. E.G. I cannot use mouse with UNDELETE (mouse cursor moving area is invalid). My be, it is a bug of the mouse driver (LCS/Telegraphics IMOUSE.COM 8.20h) or video card (CL-GD54M30/5440)? 5. DRDOS6/NWDOS7/OpenDOS do not support MS-DOS multi-config syntax. Yes, all these OSs have another features instead ("?", SWITCH, GOTO, GOSUB/RETURN...) but all these features are unknown for QEMM OPTIMIZE (and GOSUB and CHAIN not only not responsible but cause errors while optimizing). That may also make some problem if everybody installs OpenDOS over MS-DOS and wishs use old system configuration. 6 LOADHIGH not supports MS-DOS switches (/R etc). But these are essential for using MS-DOS .BAT files (even though as non-functional "dummies"). 7. IF WFW 3.11 32-bit disk access is on, after exiting from Windows all current directories on all drives always become root even if I started Windows with other current directory. 8. TIMEOUT statement in CONFIG.SYS works also with all (not only "?") next CONFIG.SYS commands if F8 boot trapping and "automatically" sets "N". That is not any serios problem, but not always convenient. 9. What and why is a MS-Windows driver, NW/OPENDOS.386? BUT I USE THIS DOS because it has: 1. A good system for undeleting of erased files and directories (preserves first letter); 2. Very beautiful CONFIG.SYS syntax; 3. Runs very safely (only DR DOS 6 was more safely but it was not compatible with WFW VSERVER.386 and some other programs); 4. Good understands QEMM UMBs if those are "visible" (then I can without any problem use HIDEVICE and HILOAD instead LOADHI.SYS and LOADHI.COM, this makes my CONFIG and AUTOEXEC very simpler if I use multi-configuration with or without QEMM); 5. "honest" CONFIG.SYS line-by-line executing (unlike MS-DOS!!!); 6. Good interactive memory management utility, MEMMAX (partial compatible with QEMM) that solves some conflicts between applications. -- Pavel V.
