Recently, carefully studied the GUI of QF.COM, streamlined its useless code, strengthened the core functions, and used new prompt messages. Please experience it!

4.COM=Disk Format Accelerator Version 2006 Designed by Luo Ming'an

Used for accelerating partition/formatting, etc. for DOS internal/external commands and tool software, for example:
4 FORMAT A: /S

Not for MS-DOS7.x with EMM386.EXE! Not to be used together with SPFDISK.EXE!

Achieve acceleration by omitting disk verification: only operations and commands involving disks can be accelerated! Disk formatting always needs to set detailed disk cylinder head sector parameters. The calculation is complex and time-consuming, and it is called repeatedly, leading to users' long waiting. Omitting disk sector verification can be completed instantly. Floppy disks/USB drives are also accelerated, no matter how large the hard disk is!

The command shell exits memory after running: does not affect the independent operation of programs that need disk verification programs.

Automatically intercept incorrect instructions: end the running program, return to DOS, prevent system crash.

Write the cache to the disk before running: prevent data loss.
4.COM=Express FORMAT.COM Shell V2006 by Luo,Ming An

Save this for later, thanks for sharing the good software

The size of the software is bluffing!!!
In fact, the core functional code of the software is very little, and most of it is used to make the GUI!
This is even more true for those written in high-level languages!

Assembly language is really powerful, like a nuclear weapon--small in size but great in energy:
I can even implement a shell version with a minimum of 98 bytes (non-resident, i.e., used and exited immediately),
and a TSR resident (can be exited) version with a minimum of 122 bytes (resident in memory 288 bytes)!
--Because of the pursuit of small size, there is no prompt information. So it is not uploaded.

Thanks for sharing

First, collect it. Thanks for providing.

After formatting with 4 FORMAT, garbled characters appeared and there was no response when pressing the warm start.

After using QF and then using FORMAT, there was no such situation after formatting.

I specifically report to the owner to see what the reason is.

RE: wangjf:
Try this version----the one I newly modified.
Also, since I have made many versions, please email (lmayylxt@pub.sz.jsinfo.net) the problematic program and description of the situation, preferably with screenshots.

LZ, the one on September 5 still doesn't work. After running 4 FORMAT, the cursor just stops moving. No response to any key pressed. But the formatting is done successfully, and after restarting, the added disk name can be displayed.

Is your system configuration:
MSDOS7.x + EMM386.EXE?
If so, the reason is
Cannot use EMM386.EXE at the same time in MSDOS7.x.
Many Chinese character systems cannot also be used normally under this configuration.

I forgot yesterday under what circumstances the test was carried out, and just tested again.

Test situation:

VM virtual machine

1. MS-DOS7.1+UMBPCI

4 FORMAT C:

After the command is completed, it returns to the cursor normally.


2. MS-DOS7.1+EMM386

4 FORMAT C:

After the command is completed, it directly restarts the virtual machine.

It turns out it's the fault of EMM386.
I wonder how the newly launched JEMM is?

I tested the latest 4.COM from September 5th in detail again yesterday. The details are as follows:

Test environment: VMware552 virtual machine

Test conditions:

1. Select MENUITEM=M2,Boot with UMBPCI + PC-CACHE
Result: Sometimes as shown in Figure 4COMJG1.JPG, the cursor stops moving after running the 4 FORMAT C: command, and no key press has any response. CTRL+ALT+DEL also has no response. Sometimes the cursor flashes all over the screen, and CTRL+ALT+DEL can restart.

2. Select MENUITEM=M2,Boot with UMBPCI + SMARTDRV
Result: Everything is normal after running the 4 FORMAT C: command.

3. Select MENUITEM=M3,Boot with EMM386(NOEMS) + PC-CACHE
And MENUITEM=M5,Boot with EMM386(NOEMS), NTFS and SCSI/USB drives support(if any)
Result: The virtual machine automatically restarts after running the 4 FORMAT C: command.

4. Select MENUITEM=M3,Boot with EMM386(NOEMS) + SMARTDRV
And MENUITEM=M5,Boot with EMM386(NOEMS), NTFS and SCSI/USB drives support(if any)
Result: Everything is normal after running the 4 FORMAT C: command.

From the above test results, as long as PC-CACHE is added, it will be abnormal. It should be that 4.COM has a conflict with PC-CACHE.
If QF is used, the above selections are all fine.

I have improved the resident environment and the amount of memory, please test.

Test situation on September 15:

Test files 4.COM(4NEW.RAR - September 14); 4.COM(QF.RAR - September 14)

Test environment: VMMare5.22 virtual machine,

1. EMM386 + SMARTDRV
2. EMM386 + PC-CACHE
3. UMBPCI + SMARTDRV
4. UMBPCI + PC-CACHE

All 4 loading modes are normal after using the command 4 FORMAT X: once.

After using the command 4 FORMAT X: for the second time, the following situations occur:

1. EMM386 + SMARTDRV
2. EMM386 + PC-CACHE
Loading modes.
After the FORMAT prompt for whether to format, choosing Y and choosing N both prompt: Hardware kernel stack fault. Screenshot as follows:



3. UMBPCI + SMARTDRV
4. UMBPCI + PC-CACHE
Loading modes.
After the FORMAT prompt for whether to format, choosing Y, the command runs and then the cursor doesn't move; press Ctrl+Alt+Del key to restart;
If choosing N, after exiting FORMAT, the cursor flashes all over the screen.
