Take this 1 step at a time.
FIRST, read ALL the manuals that came with the components.
If you bought OEM parts, download the manuals from the mfg web sites.
2. Start out with just the video card and floppy drive connected.
3. The BIOS jumper depends on the motherboard. Some Intel boards come with a 'quiet boot' feature that prevents the user from entering BIOS settings.
So, yes, you may want / need to set the jumper. But, I would wait for the second boot to do so.
Then, if you have the quiet boot feature, disable it until you are past the point of needing to get into hardware settings.
Once you have a clean boot, you want to start installing your drives and Windows.
Connect the hard drive and CD-ROM drive and verify that they are detected in BIOS settings.
Then, the proceedure for installing Windows depends on which version you are installing.
For Me, W2K, or XP, set the BIOS to boot from the CD, and follow the prompts.
For W95 or W98, you need to boot from a startup floppy.
Run fdisk to partition the hard drive.
www.fdisk.com/fdisk
www.aumha.org (article on partitioning)
Re-boot, and format at least the C: drive
Run startup from the DOS prompt.
Then, for all but XP, you need to install some drivers before you proceed.
Motherboard Chipset drivers
DirectX (check video card documentation for version required / supported)
Video card driver
Now, power down, and install any other plug in cards.
It is always a good idea to check with each hardware mfgs web site for updated drivers, and use those instead of what's on the CDs that came with them.
Once everything is running, run scandisk and defrag from safe mode.
Then, go on-line, and run Windows update.
I useually install all 'critical' and 'security' updates.
The others are up to your personal preferences.
Then, you can install your application software.
