assembly - Simple bootloader and bochs -


i have simple bootloader written in at&t syntax.

[bits 16] [org   0x7c00] jmp   $ times 510-($-$$) db 0 dw    0xaa55

i use yasm -f bin -o boot.bin loader.s compile it, , bochs run.

dd if=boot.bin bs=512 of=floppy.img bochs -q

but bochs said there no bootable device.

so, have following questions:

  1. how can rewrite at&t syntax (which construction must use instead times 510-($-$$) db 0)?
  2. what wrong bochs?

thanks!

p.s. bochs compiled x86_64 support, doesn't work bochs official arch repo.

i can't imagine why you're trying write at&t syntax if don't know at&t syntax! think "times" line be... 

.org 0x7dfe .word 0xaa55

bochs looking entire 1.44m floppy image.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
