I have an old Lenovo laptop. It originally had Windows 98 installed. Now I want to install Windows 2000, but the computer's CD - ROM is broken. So I would like to ask you experts how to install the operating system without a CD - ROM? Urgent! Urgent!! Urgent!!!

Hehe, isn't it just wanting to install Windows 2000? Why be in a hurry? Go online to find a ghost version of Windows 2000 system, copy the.gho file to a non-C drive partition on the hard disk. At the same time, place a ghost.exe program file in a non-C drive partition that is in FAT32 format. Then restart the 98 system, enter from DOS, run ghost, and restore that Windows 2000 system's.gho image to the C drive.

Sincerely thank this friend for the selfless help~! I'll give it a try!

Early in the year, I encountered such a thing. There was an IBM laptop, only with DOS 6.22, no CD drive, no USB port, no floppy drive, no network card. Fortunately, there was a serial port. So I used DEBUG to make a serial port receiving program. It took nearly 20 hours to transfer a Win95 installation version from another computer, then install 95, then use the built-in 56K modem to dial up to the Internet, and then it took nearly 10 hours to download an XP clone version. So hard.....

Thanks to this friend's attention~!

You are so awesome! You even used DEBUG to write a serial port program by yourself. Downloading XP via 56K modem, I really admire you.
Why don't you just remove the hard drive and connect it to another computer to copy data.

Hehe, the person on floor 4 is quite powerful! But compared to the legend who assembled Windows 98 using a telephone, it's really nothing: http://www.cn-dos.net/forum/viewthread.php?tid=45019&fpage=1

You are too powerful. You even use debug to write your own serial port program. Downloading XP with a 56K modem, extremely admired.

You might as well directly remove the hard drive and connect it to another computer to copy data.

At that time, I also thought about removing the hard drive, but the owner of the computer didn't allow it, saying that there would be no warranty after removing it.
Actually, writing serial port reception with debug is not that difficult

'Initialize COM1
mov ah,fb
mov dx,0
int 14

'Receive data
receive:
mov ah,2
mov dx,0
int 14
test ah,0
jnz receive

'Save

Hehe, the person upstairs is really good. Admire, give a salute first!
The debug command is collected, maybe it will be useful sometime. Thanks!

Admire your patience. If there is interlnk, using the parallel port is definitely faster than the serial port.

But if it were me, unless the owner is someone I can't afford to mess with, I definitely wouldn't go to the trouble for him.

A group of experts! But how to save the data received from the serial port using DEBUG as a normal file? Can you explain it? I'm a newbie.

Assume that the file name string is placed at CS:0100, the file handle is placed at CS:0110, the data is at CS:0120, and the data length is 10 bytes.

Create file
push cs
pop ds
mov ah,3c
mov cx,0
mov dx,0100
int 21
jc error
mov ,ax

Write data
mov ah,40
mov bx,
mov cx,10
mov dx,0120
int 21
jc error

Close file
mov ah,3e
mov bx,
int 21
