    WMI will only work if the MoBo manufacturer has supplied WMI Providers to allow WMI to get at that kind of data. Most manufacturers do NOT supply this stuff. Again, check with the manufacturer for some kind of management software package. Dave Kreskowiak Microsoft MVP - Visual Basic

    Hi, Thanks for the suggestions, I shall look into them soon (I'm a bit busy at the moment with a big coursework project). Sebastian Schneider wrote: Probably not a good idea. If the power fails during the flash, chances are that the laptop will keep running from the battery. Very good point, I shall charge it and leave it in. Sebastian Schneider wrote: I don't believe the BIOS is the problem of your recurring start-up trouble. If it was, the boot sequence should fail every time. Really? I did some research into the issue, before I came to the conclusion it was my BIOS, and found this PDF[^] which talks about the introduction of 48bit addressing support in ATA-6. On page 6 in the "Solutions exist!" section: Solutions exist! Most motherboards have built-in connectors for the hard drive and CD-ROM drives. 40-pin ribbon cables connect the drives to the motherboard. These motherboard connectors are often labeled IDE Channel 0 and Channel 1. They are also called Primary Port and Secondary Port. Both are the same. The system BIOS auto-detects the hard disc drive and issues an inquiry to get the drive's number of LBAs. The largest number it is prepared to receive may be 137GB. In this case you might check with your system manufacturer for a BIOS upgrade. Many namebrand systems have the ability to "flash" the BIOS with new firmware. This is what my BIOS is doing. It's reading the size of the hard drive as 137GB exactly. Also from the same page of the pdf: Solutions exist! Without proper support, writing or saving data past the boundary line will wrap around to the front of the file system and overwrite all of your file system information, effectively erasing your drive. This is the part that made me think it's the problem I'm having - I exceed the 137GB limit and end up writing data over the MBR, etc. Please say so if you still think I'm wrong about this, but to me it looks like this is the issue I'm having Many thanks, Will. “Accept that some days you are the pigeon, and som

    Could you please post your old DLink specs? You might be looking for a L3-Switch integrated in a router, not a router per se. Since your especially asked for a multi-port routers: The ones I know are modular frames (port extensions cost extra) and start at 10000 monetary units (Cisco Catalyst, 3Com routers), used. You might just be wanting to route out of a local network (one external connection, 4+ internal connections, which could easily be done with a L3-Switch). But without more details, I am afraid that is all I can provide you with. €dit: Mangaged Layer 3 12-port 10/100/1000-Ethernet Switch: Netgear GSM7312 (ca. 1000 USD) Unmanaged Desktop 8-Port 10/100/1000-Ethernet Switch: Netgear GS608 (ca. 70 USD) You could combine the last one with a single-port Gigabit-Router and would receive a 7-Port-Gigabit Router with Gigabit Capability for around 150 - 200 USD. If you need ADSL, I suggest using a single-port GBit-Router with integrated ADSL+-Modem connected to the same switch. Cheers, Sebastian -- Contra vim mortem non est medicamen in hortem.

About the best you're going to get is to install the Generic Text Only printer (Start/Settings/Printers/Add) and not use the driver specifically for your printer.

    If you're going to get a new NIC card, check out the ones that plug into a PCIe-1X slot. They should have 64-bit drivers... :) "Why don't you tie a kerosene-soaked rag around your ankles so the ants won't climb up and eat your candy ass..." - Dale Earnhardt, 1997 ----- "...the staggering layers of obscenity in your statement make it a work of art on so many levels." - Jason Jystad, 10/26/2001

    make sure your heatsinks are properly seated (and while you have them off the CPU, use Arctic Silver 5 thermal compound (remember, don't use too much). 2) Since you're taking the HSF off to check it anyway, I'd get something a bit beefier. If you have the room in your case, check out the Scythe heat sinks that accept a 120mm fan. They rock.

    From my understanding it will not necessarily turn off the device power.. its more like a “recommendation for the hub. (i.e if a device claims its max usage is 10ma but you use 100ma it might disconnect the device) I'm willing to test it again (on several computers) if you’ll point me to a working test application..

Password protecting a folder is extremely inefficient from both a security and administrative standpoint. Networking relies on the users access token to determine what the have access to and what they don't. Passwords are NEVER assigned to specific resources, only user/machine accounts. You have to plan your security more carefully, but it's far easier to manage. Create a group on that machine, add the users that you want to have access to that folder to the group, then modify the permissions of the folder and give the appropriate permissions to the group. Done! Now noone has to memorize yet another password. The users that have access to the folder have it without doing anything and the users who don't, well, don't have access to it.

    Only if the WMI Providers for the MoBo have been installed. Most of the manufacturers don't bother creating the providers for this stuff. Other stuff, like the motherboard and manufacturer details, yes, but not the fan and temp counters. Pity, 'cause I would like to use them myself. Dave Kreskowiak Microsoft MVP - Visual Basic

    After reloading the OEM defaults, cleaning the AGP slot and trying to start Windows (which should always work, at least in low res), I concur with John. Replacing the MB seems like the sanest thing to do now. Cheers, Sebastian -- Contra vim mortem non est medicamen in hortem.

    I believe that's a Socket 370 chip... Newegg has four motherboards that are compatible from $53 to $68.
