You probably meant SHELL=...\command.com /P:autoexec.bat rather than
%COMSPEC%, didnīt you?
%COMSPEC% is an environment variable set by the command processor
when it loads and is used to find the file on the disk to reload
the transient portion of the command processor after loading and
exitting huge applications.
Changing %COMSPEC% to point to a different command processor than
the one which is currently running may cause the system to lock up
when returning to the prompt, so you should better not play with this...

Unfortunately not, unless there would be an (undocumented) QEMM
option to override the sanity check. Anyone?

Yes, it will, and it will even free a few more bytes conventional
memory when using FILESHIGH=, FCBSHIGH=, or DOS=AUTO, but it will
cause fatal problems at least with some issues of Windows 3.xx.
So, please always remember that /you/ patched the kernel files,
and donīt blame DR-DOS (or me) when trying to run Windows
somewhen later... ;-)
For your convenience, here is the script again:

; Description: Caldera DR-OpenDOS 7.02+ DEBUG R1.50+ script to patch
; the DR-OpenDOS 7.02+ IBMBIO.COM (1997-12) file to
; allocate only 5 instead of 8 file handles during
; [D]CONFIG.SYS.
;
; Sympthom: Quarterdeck's QEMM 8 DOS-UP refuses to relocate
; DOS sub-structures on DR-OpenDOS 7.02+ and later,
; resulting in about 1 Kb less free total Conventional
; Memory.
;
; Synopsis: Due to the introduction of new FILESHIGH=/HIFILES=
; and FCBSHIGH=/HIFCBS= [D]CONFIG.SYS directives,
; the chunking of handles has slightly changed with
; DR-OpenDOS 7.02+. For unknown reasons, DOS-UP
; refuses to work with this changed layout.
;
; Solution: A patch should be made available by Quarterdeck
; for QEMM, but at present none seems to be available.
; Please keep asking them for a solution to this
; problem, as a fix is a simple two-liner for them
; and besides would also improve general DOS
; compatibility in their product.
;
; Workaround: A temporary solution is to apply this patch
; (IBMBIO85.SCR) to the IBMBIO.COM file. The patch also
; gives about 150 bytes more conventional memory on
; systems, where handles are loaded into UMBs using
; the new FILESHIGH=/HIFILES= or FCBSHIGH=/HIFCBS=
; directives.
;
; Requirements: 1. DEBUG R1.50+ (since DR-OpenDOS 7.02 and
; DR-DOS 7.02+).
; 2. IBMBIO.COM as of Caldera DR-OpenDOS 7.02 and
; DR-DOS 7.02+.
; Tested with IBMBIO.COM up to DR-DOS 7.04/7.05
; (1999-08-19).
;
; Hints: - Never try to apply this patch with other issues of
; DEBUG or to other IBMBIO.COM files then those listed
; above.
; - It is not garanteed that this patch will continue to
; work with future issues of DR-DOS, although it will
; hardly become broken, as the script will attempt to
; synchronize with new issues automatically.
; - You can query the file version number by
; toggling Scrollock on when the "Starting Caldera
; DR-DOS..." message is shown at startup, or by
; issueing "VERSION IBMBIO.COM" at the C:\ prompt.
;
; Restrictions: - Microsoft Windows 3.xx will probably not run after
; applying this patch to IBMBIO.COM. Instead, it
; will display: "Unsupported version of MS-DOS" on
; its startup, especially with handles loaded into
; UMBs. Note, that at least Microsoft Windows for
; Workgroups 3.11 still runs OK. If you have success
; running a different version of MS Windows after
; applying this patch, I would appreciate your
; feedback, just for the records.
;
; How To: C:
; SYS A: Back a backup boot floppy
; ATTRIB -R -H -S C:\IBMBIO.COM Strip off attributes
; COPY C:\IBMBIO.COM C:\TEMP\IBMBIO.COM Backup the BIOS file
; CD C:\TEMP
; DEBUG < IBMBIO85.SCR Apply the patch
; COPY C:\TEMP\IBMBIO.COM C:\IBMBIO.COM Update system if OK
; ATTRIB +R +H +S C:\IBMBIO.COM Restore attributes

No, I cannot help you with this. Iīm no DV, DV/386, or DV/X expert.
It was rarely used in Europe. But there are probably other DV* users
around here.

I never used Skipper or WebBoy, but I have excessively used DR-WebSpyder
for web-browsing under DOS until last winter. However, since DR-WebSpyder
is no longer being maintained and has a few annoying quirks, I recommend
Arachne, even if this is not an extended DOS application. For DOS
emailing I suggest to try PMAIL for DOS.

As the name says, the count of root directory entries applies
only to the root directory on FAT12 and FAT16 volumes (not on
FAT32 partitions). RAM disks usually use FAT12 or FAT16.
If you want to use a more advanced RAM disk I suggest to try
the TDSK 2.42 BETA downloadable from
ftp://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/dos/ramdisk/
