Hello. This is how:
---
ld -T link.ld -o kernel.bin start.o main.o scrn.o gdt.o idt.o isrs.o irq.o
timer.o kb.o
---

start.o is assembled by NASM and is a:
start.o: Linux/i386 impure executable (OMAGIC)
All other objects compiled with GCC.

Below is the link.ld script:
---
OUTPUT_FORMAT("binary")
ENTRY(start)
phys = 0x00100000;
SECTIONS
{
  .text phys : AT(phys) {
    code = .;
    *(.text)
    *(.rodata)
    . = ALIGN(4096);
  }
  .data : AT(phys + (data - code))
  {
    data = .;
    *(.data)
    . = ALIGN(4096);
  }
  .bss : AT(phys + (bss - code))
  {
    bss = .;
    *(.bss)
    . = ALIGN(4096);
  }
  end = .;
}

Also, to any moderators: please organize these messages if you see fit. I
am having a webmail problem which prevents me from replying directly to
the other user. Until I figure out what's wrong I can only forward my
replies.
