Shipping NetWinder FAQ
Got yourself a shiny new NetWinder? Got a few problems with it?
Maybe one of them appears below?
- Help! My clock is set to some weird value!
- Yup. It doesn't have a battery, just a big capacitor, enough for about two days. So don't turn your NW off, eh? Here's how to fix your clock:
- date -s mm/dd/yy
- date -s hh:mm
- clock -w -u
or if you've got the network configured:
- rdate time.nist.gov
- clock -w -u
or if you're using ntpdate:
- # ntpdate uses adjtime(), which cannot set time backwards.
- date -s 980101
- ntpdate www.netwinder.org
- clock -w -u
- Help! I have some files which are dated in the future!
- Yup. Obviously some people worked on the image without performing the previous step.
Fix it like this:
- touch /tmp/now
- find / -newer /tmp/now -exec touch {} \;
- Help! X doesn't work on my monitor!
- Yup. The default X framebuffer is 1024x780.
- rm /dev/fb0current
- ln -s /dev/fb0color640x480x16
- Help! The fan is always running on high speed!
- Yup. The thermostat is set way low. Set it to 50 degrees C like this:
- Help! What happened to my 3.2GB of disk?
- It's there. pfdisk /dev/hda will show it all to you
when you use its L command. 16MB of boot
partition, 700MB of root partition, 125MB of swap, and 2079MB
of /disc/hda4.
- Help! How do I set up Ethernet networking?
- No problem. Configure eth0 if you're using the 10Mbps port.
Configure eth1 if you're using the 10/100 port.
- /etc/rc.d/init.d/network stop
- vi /etc/sysconfig/network
- vi /etc/sysconfig/network-scripts/ifcfg-eth0
- vi /etc/sysconfig/network-scripts/ifcfg-eth1
- /etc/rc.d/init.d/network start
This will complain that the tulip module is already loaded. This is a harmless bug. Ignore it.
- Help! How do I set my console to get more characters on the screen?
- Pat Beirne puts setfont -9 into his rc.sysinit. Most apps handle 80x44 well.
- Help! My machine runs hotter than I think it should.
- Try powering down your hard drive after a bit.
Use hdparm -S 15 /dev/hda to power down the disk after 75 seconds.
- Help! When I move a window in X, it leaves some pixels behind and
doesn't redraw properly.
- It's a function of the X server code and kernel. The X server
performs unaligned writes, which generate a fault. The kernel doesn't
handle these properly, so the screen gets corrupted. It's a known
problem, and the CCC folks are testing a kernel which fixes it.
- Help! How do I connect an external modem and run PPP?
- Apart from the usual PPP travails, you need to do the following
(the first three steps need only be done once, of course).
- cd /lib/modules
- mv ppp.o misc
- mv slhc.o misc
- insmod slhc
- insmod ppp
- Help! My netwinder doesn't boot anymore!
- Uh-oh. You broke it didn't you? Sounds like you need Stany's boot rescue HOWTO.
