- ID:AU SuperSpool, FastDrive with QEXT.SYS
- Quarterdeck Technical Note
- by Stan Young
-
- AST's SuperSpool and FastDrive utilities can be run with
- Quarterdeck's QEXT.SYS driver, but require some special setup
- parameters since the default for these utilities is to load at
- the 1 megabyte address, which is where QEXT.SYS must load.
-
- To have it work properly, you must have QEXT.SYS invoked in your
- CONFIG.SYS file before loading FASTDRIVE. Naturally, consult the
- DESQview manual (Appendix B) concerning setting up some real
- extended memory in which QEXT.SYS will be loaded. The AST
- utilities can be loaded either in the remaining real extended
- memory or in "emulated" extended memory created by AST's REX.SYS
- driver. QEXT.SYS, as noted in the manual, can only use REAL
- extended memory.
-
- As noted, the AST utilities default to load themselves at a 1
- megabyte address and therefore, if allowed to load with the
- defaults, will overwrite QEXT.SYS and disable both QEXT and
- themselves. In order to have them load above QEXT, it is
- necessary to tell them with a command line parameter where to
- load. If you have difficulty with this, please consult the AST
- SuperPac software manual, but in general, the method for telling
- the AST software where to load is as follows:
-
- Generally, under the default to load the utility in extended
- memory, you put "/EXTM" as a parameter on the command line. As
- noted, this will load it at 1 meg. If you want to be sure they
- don't load on top of QEXT, you must enter the parameter as
- "/EXTM=0,1088." This tells the utility to load at a 1088K
- address. Since 1 megabyte is 1024K, setting the starting address
- to 1088 leaves the 64K that QEXT.SYS uses free.
-
- If you use both FASTDISK and SUPERSPL, you can use the
- "/EXTM=0,1088" parameter for both of them. This would appear to
- be a conflict; however, while these utilities do not detect QEXT
- or other VDISK-like utilities, they do detect each other and will
- not overwrite each other.
-
- Note: The above setup information also applies to the AST's
- SuperDrive utility.
