I'm not sure how the MBR boot block gets around to loading it. The MBR block loads based on an offset from the start of the partition, loading NTLDR. The NTLDR code is actually part of the file system itself, it's existence is actually stored in two locations, one before the actual file system, with a symbolic entry in the file system itself. This is why some defragmenting programs can spooge NTLDR. It's not JUST a file, it's actually in a fixed location beforte the actual file allocation tables. But NTLDR uses the BIOS for I/O, reads BOOT.INI for config, and then loads several dozen different files to get NT running. That includes reading the registry for information on which drivers to load. Gulp. Correct, The MBR snippet loads NTLDR, and NTLDR reads a sparse file table which points to the special $Boot 'file'. I guess in reality, NTLDR is actually stage1.5 thinking about it. Right, but since Windows is all plug-and-play and everything, doesn't that mean all we're really accomplishing is avoiding a bunch of yellow-bang icons in Device Manager (for the hardware that suddenly disappeared)? I mean, yah, sure, it makes things cleaner, but it's not exactly critical. No? Kinda. It also serves as a way to say 'when in this profile, ignore this device'. A laptop, for instance, may ignore the built in ethernet NIC when docked into a docking station that also has a NIC. AFAIK, Linux (-based distros) doesn't offer such a facility. Well, that depends on what you're looking for. There's no Hardware Profiles GUI dialog box thingy (and $DEITY willing, there never will be). But if you attempt to load modules for all the hardware you *might* have, the kernel will only keep the ones for hardware it actually finds. So if your NIC might be a 3Com or might be an Intel, However, in my case it's much more difficult to boot my Linux partition natively, and under VMWare without a significant amount of 'meddling'. For instance, dynamic reconfiguration of X.org, alsa configurations, NetworkManager, etc.. Profiles specifically address those issues, to the point where the registry is swapped in and out depending on which profile you're loading. Not a 'super' concept, it's simular to renaming /etc back and forth. :-D I haven't counted, but does Linux support more than a hundred-ish types of disk controllers these days? If not, I'd rather see them all available all the time ... You can. Build them all as modules, and have initramfs include all of them. Your initial ramdisk would be pretty hefty, but it would work. I believe many install disks do something simular. -- -- Thomas ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

In my case, it is one of the few solutions. At work I use WPA authentication, and home I use WEP 128, at BLU meetings I use either MIT or JABR-NET unencrypted. While Network Manager does fail, I have found the most common cause it WPA-Supplicant. Prior to using NM, I used SCPM. SCPM has a few advantages over NM. One advantage of SCPM was that at HP I could configure a proxy server, but no proxy server elsewhere. I have not seen SCPM used outside of SuSE systems, though. -- -- Jerry Feldman [EMAIL PROTECTED] Boston Linux and Unix PGP key id: 537C5846 PGP Key fingerprint: 3D1B 8377 A3C0 A5F2 ECBB CA3B 4607 4319 537C 5846 signature.asc Description: PGP signature ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Source for DVI/USB KVM switch, cables
Hi, I need a KVM switch that will, at a minimum, switch one DVI monitor at 1920x1200 and one USB port between two computers. An extra USB port and audio would be a bonus but not required. I will also need the DVI and USB cables to go between the switch and the computers. Can anyone recommend a particular brand or supplier for these? They seem to be pretty pricey. For example this unit http://www.gefen.com/kvm/product.jsp?prod_id=3113 which is $149 from NewEgg, including the required cables.

Saving the error output of make
Hi Gang, I managed, with great difficulty, (another rant, for another day) to install Scientific Linux on my Optiplex 745. This machine will suffice until I get a decent computer for what I need to do. To run some tests, I'd like to install Octave on it. (OS version of MATLAB.) I want to build octave from source so I get the options I'm interested in. (I had managed to build octave from source when I had Centos 4.6 on the computer.) The configure phase appeared to go ok. The make failed. At some time I can send to anyone if they are interested - that is if I can capture it. I tried using: $ make | tee makeoctave.log This stored nearly everything, except for the error messages near the end. So I got something like this lots of stuff ... 1] g++ .. blah blah ... 2] ../src/liboctinterp.so: undefined reference to ... 3] ../src/liboctinterp.so: undefined reference to 'std::basic:_istreamchar, 4] collect2: ld returned 1 exit status 5] make[2]: *** [octave] Error 1 6] make[2]: Leaving directory 7] make[1]: *** [src] Error 2 8] make[1]: Leaving directory ... 9] make[1]: *** [all] Error 2 In the file makeoctave.log I recorded lines 1,4,5,6,7,8, 9, but not 2 and 3?
