Hi all there , i was for 4years on my pc , learning all and nothing , now i try some free OS , and i try Damn Small Linux , damn! i cant figure out how set it up

i might thing that i need to extract the .img file by dos commands? im not sure at all
im posting this topic here , because i own a 256mb Verbatim drive , and the speed is highter then a CD  about 100mb/sec when......

and bootusb.img , somethings like that
