DR DOS and 386MAX v.7DRDOS and 386MAX 
This document explains how to install 386MAX/BlueMAX version 7 on a system with 
DRDOS 6.0. 386MAX is used as an example in all cases. 
Before you install 386MAX: Use a text editor to modify your CONFIG.SYS file. 
Remove the ?"Load memoryMAX software (Y/N) " from the line in your CONFIG.SYS 
that reads: 
?"Load memoryMAX software (Y/N) " Device=C:\DRDOS\EMM386.SYS /F=Auto /K=3072 
Add the following line to your CONFIG.SYS file after the modified line from 
above: 
DEVICE=C:\DRDOS\HIDOS.SYS /bdos=ffff 
Install 386MAX: Follow the on-screen prompts until you are asked if you want to 
run Maximize. 
When Install asks if you want to run Maximize, say NO. Do not run Maximize at 
this time. After verifying your "NO" response, Install exits to DOS. 
Check the location of the DEVICE= line for 386MAX.SYS in your CONFIG.SYS. The 
following lines should be in your CONFIG.SYS in the given order: 
HIDOS=ON 
Device=C:\DRDOS\HIDOS.SYS /bdos=ffff 
Device=C:\386MAX\386MAX.SYS PRO=C:\386MAX\386MAX.PRO 
For versions of MAX prior to 6.02: if the following two lines are present 
anywhere in your CONFIG.SYS, move them so that they load immediately before 
HIDOS=ON in the above example. For version 6.02 and later, move these lines so 
that they load immediately after the 386MAX device driver: 
Device=C:\DRDOS\SSTORDRV.SYS 
Device=C:\DRDOS\DEVSWAP.COM 
Reboot your system. 
Run Maximize: 
Type Maximize in the 386MAX subdirectory, and follow the on-screen prompts. You 
may choose to run either Quick or Full Maximize. 
Maximize will run to completion. You will be returned to the DOS prompt (or your 
own start-up configuration) after the third phase of Maximize. 
If you are using a version of MAX before 6.0: 
On initial installation, 386MAX 5.12 does not strip out DRDOS 6.0 memory 
management commands. Remove the commands manually before installing 386MAX. The 
commands to look for are: 
In CONFIG.SYS - 
Any line beginning with HIDEVICE= should be changed to read DEVICE= 
Any line beginning with HIINSTALL should be changed to read INSTALL= 
Remove the line that reads DEVICE=C:\DRDOS\EMM386.SYS /bdos=FFFF 
In AUTOEXEC.BAT - 
Remove HILOAD from any affected lines, for example: 
HILOAD SLP - should be changed to SLP 
Common Problems with DRDOS 6.0: 
If your network drivers fail to load, you may need to upgrade to a DRDOS 
compatible version of the drivers. 
If you are using Windows 3.1, use the patch for DRDOS (DR6WIN.ZIP or DR6WIN.EXE) 
available on MicroSoft's BBS. 
Error message - "This driver not supported by this version of DOS". If you did 
not allow DRDOS to make changes to your CONFIG.SYS or AUTOEXEC.BAT files, the 
driver that you were using for another operating system may not be supported by 
DRDOS. Check DRDOS driver listing for compatibility (i.e., running MS DOS - 
DOSKEY). 
If Device Drivers and TSRs are not being relocated into high DOS memory, verify 
that your CONFIG.SYS has all the lines given in the example above. If HIDOS=ON 
is present in your CONFIG.SYS without the HIDOS.SYS line (see the example 
above), the amount of high DOS memory available to 386MAX for loading device 
drivers and TSRs is decreased and Maximize will take much longer than necessary 
to run to completion.
