0. Extract the contents of the zip package to a folder.
1. Start rufus-2.6.exe. (In case of you using Vista/7/8/8.1/10 right click on the exe and "Run as administrator")
2. In the "Device" combobox, choose your flash drive or USB SD card reader. 
Other settings:
Partíciós Scheme:"MBR parttition scheme for BIOS or UEFI"
File system:"FAT32"
Cluster size: "xxxx byte (Default)" /Choose rhe one with the "Default" text/
Volume label: As you wish, for me, it was "WEBRADIO"
l l Check Device for bad block(not checked)
lXl Quick Format(check or not, as you wish)
lXl Create a bootable disk(check)
lXl Create extended label and icon files(check)

Comboboxes on the right:
[1 Pass]
[ISO image] <--on its right side, there is a CD icon, click it and browse for the "dsl-4.4.10.iso" image file.

3. When you configured all of the above, click the [Start] button and in the next window, the [OK] button

4. If the program finished, you can close it. There is one thing you need to do. There is a folder named "copytoflash".
Copy its contents: the "boot" folder and the "backup.tar.gz" file to your previously created target drive'S root directory, 
with the overwrite option in a program like eg. Total Commander.
This overwrites the isolinux.cfg file, which configures the boot of the software, and the Damn Small Linux 
and the radio client configuration settings (backup.tar.gz).,
5. You can now remove the flash drive safely from Windows. Plug it in your client, set its BIOS to boot from this, and run it :)
6. Unfortunately, newer network hardware(ethernet and wifi cards) are unrecognizable by Damn Small Linux,so old machines like
486/P1/P2/P3/K5/K6/Duron/Athlon mostly run this software correctly, it mostly works on x86 compatible systems before the P4/AMD Athlon era,
but others also worth a try.
