China DOS Union

In a friend's computer, because some bad sectors were found in the front of drive D, I used PQ to separate them out and set them as hidden partitions. However, after booting with Wengier's boot files, I can't see all the partitions after the hidden partition, but there is no such phenomenon when booting with the WIN98 on drive C (or the original WIN98 boot disk).

Well, then let's study together again and see if the same situation occurs on other machines.

I also need an IO.SYS with a logo (not afraid of logic locks). Can Wengier upload one or send it to my mailbox: PIZIGAO@ELONG.COM

The moderator is not afraid of the IO.SYS with logic lock. It can't boot on my hard disk. Also, the IO.SYS file for slimming down is the same. I have a dual boot , and IO.SYS is placed in the root directory of drive C. The original IO.SYS of 98 can boot the hard disk. When I press F8 to select to enter DOS, I just see the cursor flashing, and I can't enter pure DOS. There is nothing written in MSDOS.SYS, and there is no AUTOEXEC.BAT file set, but it can boot when made into a bootable floppy disk. I don't know why? Please give advice, thank you

The version master is not afraid of the IO.SYS with logic lock cannot start on my hard disk. In addition, the IO.SYS file for weight loss is also like this. I am dual-boot Press F8 to select to enter DOS and only see the cursor flashing, unable to enter pure DOS. There is nothing written in MSDOS.SYS, and there is no AUTOEXEC.BAT file set, but it can be started as a boot floppy. I don't know why? Please give advice, thank you

If that's the case, just add a line SystemReg=0 in MSDOS.SYS as mentioned above.

In fact, I initially used this weight-reduced IO.SYS on the hard disk, and then transferred it to the boot floppy to make it usable. I have tried many computers, and none have failed (whether there is the line SystemReg=0 in MSDOS.SYS or not, I have never failed. If I add SystemReg=0 again, then it is basically certain that there will be no problems at all).

Is it just writing SystemReg=0 in MSDOS.SYS? There are no format requirements, right? I originally didn't write anything in it.

Of course not~~SystemReg=0 should be placed under the section.

The host sees and forgives, still not working. I used the IO.SYS and msdos.sys files from your last version of MSDOS7.1. Putting them in the root directory of the hard disk just doesn't work, only the cursor is flashing on and off. Changing to the original 98's IO.SYS works, really can't figure it out.

Respect the moderator, still no good, using the IO.SYS and msdos.sys files in your last version of MSDOS7.1. Placing them in the root directory of the hard disk doesn't work, only the cursor is flashing. Changing to the original 98's IO.SYS works. I really can't understand.

Press the Shift+F8 key at startup to execute step by step and see where it fails. Also, put the C:\LOGO.SYS file.

I'm on XP system. Pressing shift+f8 doesn't work. Directly booted into XP. Usually to enter pure DOS, I press F8 - return to the operating system menu - then select MS-DOS to enter pure DOS. There are no AUTOEXEC.BAT and config.sys on the root directory of drive C, and there is no HIMEM. My BOOT.INI is written as follows:


timeout=0
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS

C:\="MS-DOS"
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect

My system is also multi-boot (from the boot menu of WinXP, you can select MS-DOS, ROM-DOS, FreeDOS, WinME, Win2K, WinXP, floppy boot, CD-ROM boot, etc.). You just need to select "MS-DOS" in the OS menu and press the Ctrl key to get the DOS boot menu, and there is the "Step by step" item in it.

Notify the moderator I pressed the Ctrl key, but there was still no response. Only the cursor was flashing. I gave up and didn't do it anymore. I'm dizzy. I just don't understand why it can boot from the floppy disk. The same IO.SYS

May I ask, what is the total size of this hard disk? How large is the C drive? What is the model? I have tried many different types of hard disks, but I have never had this kind of problem (actually, my C:\IO.SYS is this file now).

I am ST34312A 4.3G hard disk, C drive is divided into 1.61G, now available space is 591MB
