mount -o loop,offset=32256 dos-hdd.img dir

I’m using such image to update BIOSes in machines where bios doesn’t fit into floppy image. Such hdd image can be places inside iso image to be booted at virtual or real cdrom.

mkisofs -v -r -T -J –hard-disk-boot -b dos-hdd.img -o ../test.iso .


options snd-hda-intel index=1,0


Enable dmix with surround 5.1 support (no upmixing):


pcm.dmixer {
type dmix
ipc_key 1024
ipc_key_add_uid false # let multiple users share
ipc_perm 0666 # IPC permissions (octal, default 0600)
slave {
pcm "hw:0,0"
channels 6
# buffer_size 16384
}
}

pcm.!default {
type plug
slave.pcm dmixer
slave.channels 6
}


to /etc/asound.conf. Enable 6 channels in alsamixer, too.

Which means that radeon itself eats more than 16W of power (meausred with powertop). That’s more than whole notebook in integrated gpu mode. Nightmare!

Note that HD 3400 was driven by open source radeon driver which doesn’t have any power management support at this moment.

200904 update: ati driver in git contains updated power management and it’s eating ~16W here instead of ~28W now with DynamicPM turned on.

Switch TERM to konsole-256color in kde konsole terminal emulator (or whatever emulator you use – rpm -ql ncurses terminfo | grep 256 for more) and put into .vimrc:


colorscheme darkblue
highlight TabGroup ctermbg=233 guibg=233
match TabGroup /\t/


Now tab characters are a bit brighter than spaces.

and verify that IPv6 works by doing for example:

mtr -6 www.pld-linux.org


This solution doesn’t require any configuration (well, there are some options that can be altered). It should work even if you are behind some NATs and other weird gateways thanks to Teredo.

Working setup causes new interface to appear, for example:

Of course there are other solutions for non-native IPv6 like 6to4 (pure rc-scripts are enough), ISATAP (see miredo-client-isatap package) or just typical SIT tunnel.

dig @ip_of_your_caching_ns +short porttest.dns-oarc.net TXT

Example:

$ dig @192.168.1.254 +short porttest.dns-oarc.net TXT
z.y.x.w.v.u.t.s.r.q.p.o.n.m.l.k.j.i.h.g.f.e.d.c.b.a.pt.dns-oarc.net.
"x.y.z.q is GOOD: 26 queries in 5.0 seconds from 26 ports with std dev 17652.90"


Mount it and copy contents of PLD RescueCD like x86 and x86_64 ISO image to that partition, to /rcd subdirectory.

Make MBR record:

ms-sys -s /dev/sdX

(where sdX is entire flash disk; ms-sys comes from ms-sys package)

Copy syslinux configuration for USB to root directory of your flash drive as syslinux.cfg. DOS/Windows image should be placed in /rcd/boot/dos.gz (compress it with gzip first).

Run:

syslinux -s /dev/sdXY

to load syslinux onto your flash drive.

Reboot your system and check if it boots correctly

Note that some systems have problems with booting from flash driver (especially big like 1G or 2G flash drives).
