- Problems with MS DOS V5.00 and COMMAND.COM & Novell Netware V3.11 & 2.2
-
- 1st problem seen was with an ARCNET lan card and boot rom.
-
- - create a boot floppy with MS DOS V5.0 on it.
- - put the network shells on (ipx & NET5 or NETX)
- - test it in a unit with a floppy to make sure it works.
- - DOSGEN it, and rplfix.
-
- Diskless work station will boot DOS, then run ipx, net5, and allow
- you to login to the network. When LOGIN.EXE exits you get a message
- as follows:
-
- Invalid COMMAND.COM
- Cannot load COMMAND, system halted.
-
- We tried several different Arcnet lan cards, boot roms, and settings (INT,
- I/O and RAM). All gave the same response except the Novell RX-NET boot
- rom (Remote reset V2.1, PN#817-234-020 REV A), it hung after loading
- IPX and NET5. We also downloaded the latest IPX and NETX files from
- Netwire, they gave the same results.
-
- We tested an NE2000 lan card with boot rom, it worked just fine??? Or
- at least we thought it did.
-
-
- 2nd problem MS DOS V5.00 again, LOGIN.EXE V3.58, and NO EXTRA ENVIRONMENT.
-
- - If login.exe tries to set more environment than there is space for,
- you will get the same Invalid COMMAND.COM system halted message as
- above.
-
- - If you give the system more environment (shell=command.com /e:800/p)
- the problems seems to go away.
-
- - If you change the LOGIN.EXE to V3.08 the problem also seems to go
- away.
-
-
- 3rd problem MS DOS V5.00 again, and some programs.
-
- - Upon exiting some programs you will get the same Invalid COMMAND.COM
- system halted message.
-
-
- All three problems have been seen on four different customers networks and on
- our own in house network. In the case of the customers we have moved them
- back to MS DOS 3.3a.
-
- Common to all 5 networks:
-
- Only two copies of COMMAND.COM on the network as follows.
-
- SYS:\PUBLIC\IBM\MSDOS\V3.30\COMMAND.COM (25,308kb 02-02-88 12:00am)
- SYS:\PUBLIC\IBM\MSDOS\V5.00\COMMAND.COM (47,845kb 04-09-91 5:00am)
-
- the second V5.00 command.com is the same size and date as the boot
- immage or floppy/hard drive.
-
- the S2: search drive is set to the above path as follows
-
- MAP ROOT S2:=SYS:\PUBLIC\%SMACHINE\%OS\%OS_VERSION
- COMSPEC = S2:COMMAND.COM
-
- when you type SET at the dos prompt the COMSPEC=Y:COMMAND.COM
-
- If you type COMMAND from any ware on the network, it loads a
- copy of command.com with the proper message. You can then type
- EXIT without any errors.
-
- In the 3rd problem listed above if you first type COMMAND in the
- same directory as the file that gives the error on exit, command
- will load another copy without any error.
