Booting NetBSD/mac68k

Pages in Japanese

Now, it is time to try to boot NetBSD.

  1. As INSTALL guide says, I first made "A/UX Root & Usr" partition and "A/UX Swap" partition. Then, I ran "mksf" to initialize the partition, and used "MacBSD Install Utility" to install "base11" and "etc11", and to build devices.
  2. I also used "MacBSD Install Utility" to copy the kernel. After "MacBSD Install Utility" launched, I selected "Mini Shell" and typed 
    cpin (the path):netbsd netbsd.test
    (the path) indicates the full path of the directory.(separated with ":")
  3. I setup'd "Booter" appropriately, and started booting. Nothing happend. [Mar 96]
    I first thought it was a booter problem, but after a week or so, (I compiled the booter sources and checked it.) I recognized that the booter works correctly.
  4. I needed to know where on earth the program stopped. Since the videoaddr was 0xfe200000, I added "movel #0xaaaaaaaa,0xfe200000" in some places in locore.s changing the address(plus 0x4). It shows a short gray line on the screen. And I found it stoped in setmachdep() in machdep.c .
    In setmachdep(), the booting stopped at line 
    via_reg(VIA2, vIER) = 0x7f;	/* disable VIA2 int */
    (found by using gray_bar().)
  5. It seems that VIA2 is not at 0x50f02000. [Apr 96]
  6. Since the VIA2 problem seemed to be fixed, I ftp'd the newer kenerl sources from NetBSD-current. [May 27 96]
    I patched JPW's adbpatch and HAMADA's pmpatch, and built the kernel. I succeeded to boot it with the single user mode but only with the external monitor. [May 30 96]
  7. I changed all '.long 0xf0100800' in get_pte() in locore.s to '.long 0xf0100c00' which mean to use the tt1 register instead of the tt0 registre. Then re-built the kernel. It booted without an external monitor! [Jun 8 96]
  8. I installed NetBSD1.1, and I scceeded to run X with the external monitor. [Aug 1 96]
