Hauppauge 500 woes

by Mike

I've been working on setting up a MythTV box with a Hauppauge 500. The reception I am getting is a bit grainy. I read that it could be the firmware, too high of a signal, or too low of a signal. I took care of the firmware last night by following the directions on their wiki. The picture is still a bit grainy. Before I go out an buy a signal booster I was wondering if anyone had any ideas or experience with the 500. ~Mike -- They who would give up an essential liberty for temporary security, deserve neither liberty or security --Ben Franklin

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Did you use udev? There's a spot about using a certain profile if you're using the 2.4. Udev only works on 2.6 and up (and not on some of the older 2.6 kernels). Reboot with the livecd chroot, enter the chrooted environment and check your kernel config for DEVFS. Make sure it's compiled in (Not a module) and it's set to mount automatically at boot. Also, make sure that udev isn't installed (emerge -s udev) and if it is uninstall it (emerge --unmerge udev).

This will list the OBP tree for you (it's a port of the solaris version of the command). In order for the command to work, though, you need to have the device /dev/openprom. This is an option in the Kernel. So, without having to worry about size limitations, this is not really a critical issue. but if you want to slim the kernel down anyway, compile a larger kernel for now that includes /dev/openprom and then use prtconf to figure out what you need / don't need for your next compile. There is also an eeprom command (/usr/sbin/eeprom) which should provide you with similar info ... Then to save you some more disk space (if you are concerned about that, too), you can gzip -9 your kernel, and SILO will decompress it itself at boot time (just takes a couple extra seconds to boot the box). --Adam > _______________________________________________ > Wlug mailing list > Wlug(a)mail.wlug.org > http://mail.wlug.org/mailman/listinfo/wlug

Re: [Wlug] New ULTRA1 success - almost

by Adam Gomes

Ahhh ... one lovely advantage to Sparc, is that it doesn't have the same silly size limitations that x86 does. So ... _don't_ worry about the size of the kernel. If you have room in memory, it will load. In fat, my own kernel on my Ultra 10 is 3.3MB. That's one reason why there is no "make zImage" for sparc. Of course, a smaller kernel means lower memory utilization, and that of course has its own benefits, but it's not necessary to do all that slimming that is needed for x86. Also, if you want to save some space on your disk, at the cost of a little bit of speed at boot time, you can just gzip -9 your kernel. I did this, myself. The SILO boot loader is smart enough to notice that it is a gzipped image and just decompress it itself. See on my own machine: gomer@callisto:/boot$ ls -l vmlinuz* lrwxrwxrwx 1 root root 20 May 18 2005 vmlinuz -> vmlinuz-2.4.18-sun4u -rw-r--r-- 1 root root 1379575 May 18 2005 vmlinuz-2.4.18-sun4u gomer@callisto:/boot$ file vmlinuz-2.4.18-sun4u vmlinuz-2.4.18-sun4u: gzip compressed data, was "vmlinux", from Unix, max compression gomer@callisto:/boot$ cp vmlinuz-2.4.18-sun4u ~/kernel.gz gomer@callisto:~$ gzip -d kernel.gz gomer@callisto:~$ ls -l kernel -rw-r--r-- 1 gomer gomer 3371524 Apr 15 09:06 kernel gomer@callisto:~$ file kernel kernel: ELF 64-bit MSB executable, SPARC V9, version 1 (SYSV), statically linked, not stripped (not even stripped), lol. So, please, don't lose any sleep over the size of your Kernel ... not on Sparc64 at least. --Adam On Fri, 2007-04-13 at 17:51 -0400, Eric Martin wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > I realize I may need to qualify my last post. by 'Make as many modules > as possible' I meant what Mike said.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I realize I may need to qualify my last post. by 'Make as many modules as possible' I meant what Mike said. Anything that you don't need to get the root filesystem is a good candidate for a module.
