    So would I want an uninteruptable power supply or a line conditioner. Or are they the same thing? Just wondering if that is what I should be asking for. Will they still work off a strip?
    I have an APC 1200VA Line Conditioner, which has an Auto transformer in it, so it ramps the voltage up or down according to the input mains voltage. Essentially a UPS is the same but with a Battery and inverter so it can (depending on size) provide power whilst there is a blackout.

    But like all things in this world there are some caveats and variables. In say getting a cheap UPS you might get depending on it's capacity and what you are doing on the PC when there is a blackout, say for example 20 minutes of usage. However a cheap UPS might not provide as good as Brown out protection than a reasonable dedicated Line Conditioner.

    Then there is another issue that can sometimes be a problem with some PSU's and that is the way The UPS Inverter creates an AC wave form. They tend to provide a "synthetic waveform" or one that matches an expected mains supplied AC waveform you'd expect to see (ie a sine wave) if you checked the mains supply with an oscilloscope.

    On the can you use a UPS or line Conditioner on a power strip, surge or non surge is something manufacturers sometimes mention. Most don't want you understandably "daisy chaining" electrical connections. Sometimes you can use a longer IEC lead on the Line conditioner/UPS, then if you say have 4 IEC outputs, you can plug individual items in, but use one to power a strip, ie IEC to 2pin/3pin mains sockets (belkin used to sell that connection, not sure if they do now and/or if they do in your region).

    This is the US site (i'm in the UK) and these are the newer line-r voltage conditioners APC do and as per the old models 600 & 1200 VA versions.

    So here I am dealing with problems again with a completely different set up and case. I don't think the PSU tester would do me much good as I could go a few days without seeing the brown out.
    I would still also suggest you test your PSU as well. If you want I could find you cheaper PSU testers, but that one is about as good of quality you can get without being cheap and useless.

    Hi VorLonUK

    Nice to see your expertise back in the forum! Hope all is well with you.

    Hi LsdMe,

    I was "summoned" back by a private message alert email, with a guy asking me about flashing bios with a Floppy and what files could be removed from the standard Floppy creation by windows so that he could fit the 1024KB Bios Image file on it. But he has yet to return!
    I may add something to the bios update thread.

    Be interesting too, to see if Win7 still creates a bootable floppy (with same Dos files) as XP and Vista does and if of course any Bioses are using a larger Flash Image than 1MB, which would completely remove the option of a floppy disk (1.44 type)

    Ahh, well nice to see you back. I wasn't sure where you ran off to

    I always use 2 floppies when doing that myself, one MS-DOS boot disk and one with just the .Fxx BIOS file

    I do believe windows 7 still makes the same disk. Ya, you are right with the new 2MB BIOS files floppy recovery or flashing will not be an option anymore.

    I don't think Windows 7 creates a bootable floppy. You can of course format it to contain system files in disk manager. The actual option to create a "Rescue Disc" burns a CD with the essentials like the Recovery Console, diskpart, fix boot, fix MBR etc etc.

    Well we are talking about creating a bootable MS-DOS Disk using the format floppy option, I was unsure if this was carried over into the final as I only have the beta in Vmware. Guess I need to grab the final and get it installed for testing soon anyway so I will check this out.

    In that case, yes you can definitely do it. A better alternative are the 3rd party apps out there that will create one using the boot files of your choice. Simply point it to the boot files you need.

    You can also download from various sites boot floppies from Win95 and Win98.
