Error occur when I'm compiling the .asm file #6

Closed WinsDominoes closed 5 years ago

Hello, I have an error while compiling the .asm file to .bin or .iso This is the error:

WinOS.asm:161: error: TIMES value -5 is negative

I downloaded your source code of the Hello World Extended OS Version in your blogger site. And the error occur in this line: ;/////////////////////////////////////////// ; boot loader magic number times ((0x200 - 2) - ($ - $$)) db 0x00 ;set 512 bytes for boot sector which are necessary dw 0xAA55 ; boot signature 0xAA & 0x55

Please help because, I cannot convert it into .iso or .bin. Linux Distro: Linux Mint Cinnamon 19 Thank you.

Well i didn't get this error on my machine. This line tells the assembler how many bytes required to build assemble in that number of bytes(which are 512 bytes here for boot signature). Have you tried to assemble simple helloworld code ?

Not yet but, today I will try @pritamzope

I already tried the Hello World Code, It worked, but I also try again the Extended Version. It worked also.
