Btw, did you set bootable flag for the partition with Gentoo?

This was it. It all works now.


That is ... weird

To the best of my knowledge, nothing in Linux pays any attention to the state 
of the bootable flag. Some apps set it so as not to confuse Windows.


There must have been something in this thread that I missed



It is the BIOS that require the bootable flag.

Some BIOSes seem to only boot from USB if there is a bootable partition 
on it.

 If you are using a lot of memory in your computations, then
 the 64-bit environment will be much friendlier to you :)
 Also, if I understand correctly, you will get higher
 precision on floating point calculations (someone correct me
 if I am wrong here!)  I also believe that the 64 bit
 processors are able to perform more instructions per second
 on average when executing 64 bit code vs. 32 bit code if I am
 not mistaken...

I am not sure, but that makes sense.  If nothing else, things executed
directly usually run more smoothly than those who are run through
emulation.  64bit code on 64bit processor good...


There is no emulation involved when running 32bit code in either core2
nor amd64 processors. The difference when running in 32bit mode is
that some instructions are unavailable, you have a smaller number of
registers, and the registers are only 32bit.

More registers speed up most kind of code, 64bit registers speed up
64bit calculations, and the extra instructions are good for array
calculations and similar (more sse instructions for example).

The only bad thing with 64bit code is that the programs get bigger,
which may effect memory performance negatively. But if you have a lot
of memory then you will benefit from not needing any special
addressing modes.

Since you (Denis) are doing a lot of mathematical calculations you
will probably benefit from running in 64bit mode.

I have been getting this for some time but was hesitant to post a bug.
Although I get this message, my raid starts fine, and when shutting

I believe the reason for this is that your partitions are of type 'fd'
When they have that id they are automagically found and started by the
kernel, and therefor there are nothing for mdadm to do.
But this is just a guess.

Re: [gentoo-user] Issues with Gentoo WinXP dualboot setup

2006-06-05 Thread Andreas Claesson

On 6/5/06, Dmitry Mashkovskiy [EMAIL PROTECTED] wrote:

Hello,

I've successfully set up Gentoo on the machine with ABIT IS7 motherboard
and two SATA disks (integrated controller on ICH5 chipset, I guess). The
first one is Seagate (Ch2 M. (master?) in BIOS) with WinXP, the second
is Maxtor (Ch3 M. in BIOS) with Gentoo and GRUB in MBR. One problem is
that I cannot boot in Windows while booting with GRUB. Here is my grub.conf:
-
default 0
timeout 10

title=Windows XP
rootnoverify (hd1,0)
makeactive
chainloader +1

title=Gentoo Linux 2.6.12-r6
root (hd0,0)
kernel /kernel-2.6.12-gentoo-r6 root=/dev/sdb3 irqpoll
-
I get only

Booting 'Windows XP'
rootnoverify (hd1,0)
makeactive
chainloader +1

and then machine hangs. So I have to set Seagate drive as a boot device
in BIOS in order to boot Windows. How can I work it out? Should I
install GRUB in the MBR of Windows disk?
Another problem is that sometimes machine freezes or falls in kernel
panic while booting Gentoo (usually on probing ATA devices). I suppose
it may be due to buggy/broken hardware but it would be nice to find some
solution or workaround.



I believe the problem is that Windows expect to be installed on the first disk
and when it is not it fail to start.

Try adding this before the rootnoverify line:

map hd0 hd1
map hd1 hd0

This will make the bios change the order of the disks and Windows will
hopefully be happy again.

  But one way to speed this up is to use CDB, so that instead of keeping

  There are directions here:
 
  http://gentoo-wiki.com/TIP_speed_up_portage_with_cdb
 
 
 Interesting ... and thanks for the tip.  I am concerned about all the
 warnings of breakage though.  I need this on my server, which is my
 production firewall at the moment.  I would hate to have this fail.


A safer way is to update to a newer version of portage.
In portage-2.1 the cache update code is rewritten and it is much faster
then before (but maybe not as fast as CDB).

The biggest reason for the slower update now compared to a year ago,
is that the total number of packages in the tree have increased. The old
code did not handle this very well.

Since this is a server, you probably don't use kde. Excluding all kde split
packages from the portage tree will speed things up a lot.
Create an rsync exclude file and add  RSYNC_EXCLUDE=path_to_file to
your make.conf.  Look in man pages for rsync for details.

  I investigate what was in the archives, so i saved a copy (using 'C'

  hexedit and see that LATIN SMALL LETTER A WITH ACUTE is encoded with
  this hex: C3 A1 (which is not 00 E1 from unicode chart from

 I think this is just the way these characters are represented in utf-8.

Yes, it is.

00E1 hex is '000 1111' in binary.

When encoding this as UTF-8 this value is stored in two bytes.

The last byte will begin with '10' followed by the last 6 bits of data. 

'10 11' binary or 'A1' in hex.

The first byte will begin with '110' to indicate that it is a two byte 
character followed by the remaining significant data. 

'110 00011' binary or 'C3' hex.

This is correct.

The problem seem to be that mutt(?) takes this UTF-8 encoded data
and encodes as UTF-8 again as if the data was two 8 bit characters.
 
'C3' then becomes 'C3 83' and 'A1' becomes 'C2 A1'

Yes, USE-flags.

To see which USE flags mplayer uses:

$ emerge -pv mplayer 

enable them by adding them to the global USE in '/etc/make.conf' 
or add a line to '/etc/portage/package.use'. 
See the portage man pages for more information:
