Quote: NOTE: Logitech’s MouseWare for DOS/Windows 31/95, version 7.1, is a MUST HAVE FOR ALL DOS/WINDOWS USERS! Download it from: 1. UPDATE: LOGI71.ZIP is not available on AOL anymore! 2. http://www.logitech.com/TechSupp/2122.htm (where you can find ONLY the old version 6.43 of Logitech DOS/Win31 mouse drivers and the NEW version 7.2 of Win95 only Logitech virtual mouse driver). 3.

UPDATE: LOGI71.ZIP is zipped by Video On Line FTP Site: http://www.volftp.vol.it ftp://ftp.volftp.vol.it email: ftpsw@vol.it and contains Logitech MouseWare Drivers version 7.1 for DOS/Windows 3.1x and version 7.2 for Windows 95. This update appears courtesy of: jezek@ure.cas.cz 4. Another FTP server that has LOGI71.ZIP posted: ftp://ftp.cyberbox.north.de/pub/misc/drivers/misc/logi71.zip I tried it, but couldn't download. Anyone else try it............................ |

It's too long. I took a general look.
I can make the free conventional memory reach 632K by using QEMM386 with 4DOS. If I reduce the environment variable space of 4DOS a bit (since I really need that much), I can even reach 634K.
If I use the new mouse and CD - ROM drives now, I can save more upper memory. |

Your SYSTEM is a bit smaller than mine. What exactly is your upper?
Your basic memory is at most 640K, but mine is only 637K. This is probably related to the motherboard. |

Conventional memory should theoretically be 640K. In some cases, 639K is also normal. But your 637K, according to the past DOS situation, must have a virus, but according to the current machine configuration, it's not known if it's the reason mentioned by "Fujian ABC".
Free conventional memory reported by MEM:
Memory status listed by QEMM itself:

Suggest the above friends to post your AUTOEXEC.BAT and COBFIG.SYS for everyone to see.

There are too many posts. My two files are more than ten and twenty-something K respectively, and they are still being modified continuously. Moreover, the basic structures are all the same, and it's just that the content loaded is different. If you have any questions, just feel free to ask.

Strong! But after booting from the MSDOS 7.1 boot disk, there are about 610K left in the conventional memory. What advantages will there be after the foreigners optimized it to over 630K? Is it that the disk reading and writing will be faster after optimization? In DOS, I am already satisfied with 600K left in the conventional memory, but my most concerned issue is the hard disk reading and writing speed.

qemm386 is indeed powerful, but the file size is too large to be used for a boot disk.

No, my boot disk uses QEMM386.SYS. Of course, I also use HIMEM.SYS + EMM386.EXE (mainly to prevent compatibility issues). A floppy disk has such a small capacity, you can't include all functions. Everyone can make it according to their own preferences and habits. Therefore, my system starts with a single disk, one or several tool disks, one Chinese system disk, and others are made as needed.

Floppy disks have limited capacity and are easily damaged. Why not use USB drives

You know, not all machines support USB drive booting. At least my own machine doesn't. As for the CD-ROM, it's fixed and can't be modified. Of course, don't say let me use a RW disc to burn it. Originally, I also had the idea of using a 2.88M floppy disk as a boot disk, and later I also had the idea of using ZIP, LS120, EZ-FLYER and so on. Hey... unfortunately, they haven't become popular.
QEMM386.SYS is the same as EMM386.EXE. As long as EMS is enabled, the CPU's operating mode is in V86 mode. According to my understanding, as long as DOS can use more than 1M of memory, the CPU should be in protected mode. But I'm curious that if only HIMEM.SYS is used to enable XMS, the CPU is still in real mode. I haven't figured out this problem yet. And QEMM386.SYS, whether EMS is enabled or not, even if only XMS is used, the CPU is in V86 mode. I think it may be that the memory management mechanisms of the two are different. I haven't used other memory management programs much. Those who have used them can talk about it. In fact, it's not necessary for us users to deliberately care about what working mode the CPU is in, and it's not something we can change manually. At that time, the program will switch by itself. Just like some programs that need DOS4GW.EXE to run, you don't need any memory management, and then it will automatically switch to protected mode to run. |
