! 100: <p>
! 101: Note that this information may apply to other models too. To get the machine
! 102: to boot up with a serial console, make sure the keyboard is unplugged when
! 103: turning on the machine. The serial console runs on serial #1, at 9600,
! 104: 8N1 by default.
! 105: </p>
! 106: <p>
! 107: It is also possible to do a "<code class="code">setenv console d</code>" in the PROM
! 108: monitor to get the console to serial #1, or a "<code class="code">setenv console d2</code>"
! 109: to get it to serial #2 (default is "<code class="code">g</code>"). Optionally, the console's
! 110: speed can be set with "<code class="code">setenv dbaud <bps></code>". After setting
! 111: these PROM variables either do an "<code class="code">init</code>" or a reboot of the
! 112: machine.
! 113: </p>
! 114: <p>
! 115:
! 116: When booting up IRIX on the console, logins on the serial console
! 117: might be disabled. You can enable them by editing /etc/inittab
! 118: and adding the following line:
! 119: </p>
! 120:
! 121: <pre class="programlisting">st:23:respawn:/sbin/getty systty co_9600 # serial console - HF</pre>
! 122:
! 123: <p>
! 124: Don't forget to re-read the inittab then with "<code class="code">init q</code>".
! 125: </p>
! 126: <p>
! 127:
! 128: The serial port pinouts are the same as SPARC systems' serial ports, so
! 129: Macintosh serial cables work great for serial-console cables, as long as
! 130: you are willing to do it without hardware handshaking lines. See the <a class="ulink" href="../../docs/Hardware/Misc/serial.html" target="_top">NetBSD Serial Port
! 131: Primer</a> for more information.

! 137: <p>
! 138: Here's a method to set the ethernet address that works on at
! 139: least the Indy, and perhaps also other machines with HPC3's.
! 140: </p>
! 141: <p>
! 142:
! 143: All disclaimers apply yadda yadda.
! 144: </p>
! 145: <p>
! 146:
! 147: At the PROM prompt:
! 148: </p>
! 149: <pre class="programlisting">dump -w -x 0xbfbe04e8</pre>
! 150: <p>
! 151:
! 152: Sanity check the output here to see if it matches the address
! 153: given in the 'ec0: bad ethernet address' error message. If not,
! 154: you may not want to overwrite whatever is there instead.
! 155: </p>
! 156:
! 157: <pre class="programlisting">fill -w -v 0xGG 0xbfbe04e8
! 158: fill -w -v 0xHH 0xbfbe04ec

! 164: <p>
! 165:
! 166: Where GG:HH:II:JJ:KK:LL is the intended ethernet address. It's a
! 167: very good idea to reuse the address the machine was shipped with.
! 168: Check the back of the machine if you cannot remember it.
! 169: </p>
! 170: <p>
! 171:
! 172: Power down, wait one full minute and then power up. All variables

! 179: <p>
! 180:
! 181: The PROM tftp client on SGI machines can fail with default NetBSD tftpd
! 182: settings. The problem is that your current PROM may not support port
! 183: numbers with the sign bit set. The workaround is to limit the port
! 184: numbers of anonymous connections to 32767. The following tunables
! 185: should fix your problem:
! 186: </p>
! 187: <pre class="programlisting"># sysctl -w net.inet.ip.anonportmin=20000

! 193: <p>
! 194:
! 195: There are a few gotchas depending on your PROM version and the
! 196: OS (SASH) version installed:

! 198:
! 199: <div class="orderedlist"><ol class="orderedlist" type="1">
! 200: <li class="listitem"> Old versions of SASH have an issue with incorrectly reporting
! 201: the memory map. If the kernel panics with a UVM related message
! 202: on boot (even before the copyright message), try booting the
! 203: kernel directly from the PROM rather than via sash (An I2 also
! 204: had this problem before upgrading to IRIX 6.x -- it was running
! 205: 5.3 before).</li>
! 206: <li class="listitem"> Another old PROM issue -- old PROMs don't understand ELF, so

! 217: When installing NetBSD using sysinst, it will leave space at the start of the
! 218: disk for the partition that will be used by the PROM to load the bootloader,
! 219: etc. This partition is called the Volume Header.
! 220: This needs to be a minimum of 3135 blocks (see SGI_BOOT_BLOCK_SIZE_VOLHDR in
! 221: <code class="filename">/usr/include/sys/bootblock.h</code>). An example disklabel is
! 222: shown below. Partition <code class="code">i</code> will be used for the Volume Header as

! 254: After installing NetBSD, you can use the sgivol utility (located in
! 255: /usr/mdec) to manipulate this partition. If not set up already, it must be
! 256: initialised (N.B. sysinst will set this up correctly):

! 259: <p>
! 260: To upgrade the bootloader (or change it if the disk is moved to a different

! 262: </p>
! 263: <pre class="programlisting">sgivol -d boot sd0</pre>
! 264: <p>
! 265: Next, copy the appropriate bootloader as filename 'boot' into the
! 266: volume header:
! 267: </p>
! 268: <pre class="programlisting">sgivol -w boot /usr/mdec/ip2xboot sd0</pre>
! 269: <p>
! 270: You can have multiple bootloaders present (with different
! 271: names). This is very useful when booting different versions of NetBSD
! 272: (e.g., to upgrade from NetBSD 3 to 5.0 using a new INSTALL kernel) as
