The only which I remember rumors are grub. But being a bootloader, that probably doesn't hurt much. Fact is that I run pure 64bit Linux since months on my home desktop (though I'm not the typical desktop user;-). I know people were working on openoffice, but it has been sufficiently unstable both 32bit and 64bit that it's hard to ever tell when openoffice is really working right. :) I'm not an OOorg power user - it's more a .doc/.xls viewer for me. How is mplayer with w32codecs doing on 64bit? How about java plugin? flash v9 plugin? No official flash (which always everyone uses) but there is a free replacement project somewhere which AFAIK works on 64bit. But I don't know how good this (and I'm in no need for flash - I can live without youtube;-). The few movies I want to look ran with one of mplayer, totem or xine (but seldom with all). I never looked in to though. [...] In short: FUD?! No, theoretically you could have code with so many pointers that the doubling of size of pointers actually costs enough memory bandwidth to make a difference. I hope nobody writes code like that. I was just ACK - in theory. ACK - and since that software (also) needs to be fixed. Therefor I'm counting this in practice as an non-issue. trying to be thorough on any disadvantages too. Probably irrelevant on an AMD, but might hurt on a multi cpu intel since they still have much more limited memory bandwidth available. Hmm, any better numbers on it (or links to places with them)? Some browsers (konqueror, firefox as far as I've been told) allow to run 32bit plugins from the 64bit version. Since the flash-plugin and others is not really important for me, I don't really care. Well they are important to a lot of people. The new ability to run Yes, very probably. 32bit plugins certainly helps too. ACK. Or install 32bit libs and run a 32bit browser/application on the x86_64 installation. Except that is a bit of a pain and doesn't fit dpkg/apt very well. On FC6 (IIRC) it took 80 i386 RPMS just to install OOorg. The problem is not really the disk space for it (or the time and resources OOorg needs to start) but that `yum upgrade` also pulls new i386 packages which are not realy needed on the next update just because the x86_64 version is upgraded. So unless you cleanup regularly you end up with all of them (or you ignore i386 in yum.conf and temporarily add it if some dependency lib of OOorg wants to be updated - which is awkward too). Yes, but that implies Vista there and God knows how compatible (even to pre-Vista Windoze) the result will be. Well there was 64bit xp although few used it (often due to lack of drivers for their hardware. Hooray for closed source drivers!), and :-) certainly a number of programs do not officially support 64bit vista yet even though they support 32bit vista and 32 and 64bit XP. I guess in a year or two when people start wanting to use 4 or 8GB ram on their desktops they won't have a choice anymore and things might start working in 64bit windows world. That reminds me of a TYAN mainboard (Toledo i3100/S5207, Intel E6600 CPU on it IIRC[0], Ubuntu + self-compiled kernel on it IIRC[0]) bought in March 2007 which ran fine with 4GB but didn't even boot[1] with 8GB RAM (and RAM is on their recommend RAM list for that board) and stopped with an BIOS error not mentioned in the manual. The third BIOS update - to a beta version - (since March) seems[1] to make it work now. Bernd [0]: It is not back online yes so I can't `ssh` into it. [1]: To be more exact: It booted 5 times completely without any problems and then it stopped booting (when I was with at the hosters place to put it onthe Internet, God I was fed up with it and cursed it to hell!). So the seems needs probably some time and several more reboots to generate more confidence. -- Firmix Software GmbH http://www.firmix.at/ mobil: +43 664 4416156 fax: +43 1 7890849-55 Embedded Linux Development and Services -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I actually remember working with an IBM desktop once where IBM said the machine supported up to 512MB ram, while Crucial said it supported 1GB of ram. Apparently IBM only documented what they had actually tested, while the chipset could theoretically support 1GB just fine (as could the bios).

Interesting how this gives a rather different view of memory bandwidth than that: http://www.tomshardware.com/2007/10/29/intel_penryn_4ghz_with_air_cooling/page32.html Seems the AM2 easily beats the core2 on either P35 or X38 chipset. Seems the AMD managed just under 9.2GB/sec using a 6400+, while the intel managed just under 6.4GB/sec using an overclocked QX9650 at 4GHz. Sure means the AMD gets much closer to the theoretical number, while the intel manages barely half of the theoretical number. Now if those are bandwidth between cpu and mainboard, then it makes more sense since the FSB on the intel does have more bandwidth then hyper transport.

What is port 2703 ? Nothing special. Well tor seems to be assembling quite some networking infrastructure. Utility http servers like privoxy or eisfair (used with TOR) can be configured to connect through unusual ports. Astaro anti-spam update also used port 2703.

Well toms hardware had a test of the new intel 45nm quad core certainly showed that for memory bandwidth even the slowest AMD has quite a bit more bandwidth than the brand new top of the line intel.

Every time you add a socket to an AMD server you get another complete memory controller with bandwidth, while on an intel system you get another cpu trying to use your existing front side bus bandwidth. This is probably the main reason the opterons scale past 2 socket systems and xeons do not.

ACPI could also be affected by BIOS bugs. You could try booting with the option 'noacpi=1' from the boot loader for the installer. You could check if the bios has a 'PnP OS Installed' option.
