what's next? (error after BTX started)

[user local]

This computer I'm writing from is a Compaq Evo D310m/845 r BU ALL
I found enthusiastic articles about FreeBSD, so I decide to download the 
stuff (FreeBSD5.4RELEASEi386) and I start to load it.

The result follows...
Building the boot loader arguments
Looking up /BOOT/LOADER... Found
Relocated the loader and the BTX

I was advertise by a small banner that the computer was designed for an 
obscure system produced by a company in Redmont, somewhere in the West o 
USA, Windows XP, but I didn't mean it. Is that true? I'd like to deny this, 
but I'm not so good to provide an argument, i.e. installation w/ 
1280x1024x32/70Hz X Windows. Hope you will help me guys, until my boss 
change his mind of Open Source and Friends (however, take your time, various 
linuces worked on this box).

But seriously, I noticed that something strange is happening w/ booting even 
Micro$ on theese boxes, as well on some compaq laptops: the only floppy I 
manage to boot from was a Partition Image one, and when I installed an Open 
on a laptop, I discover a hidden partition at the begining of the hard disc. 
Several Live CDs and other booting CDs stuff, an W2k including, also failed. 
I have 20 boxes like this, and that's happend not only on a specific one, so 
it can not be a CD drive problem.

Help me, please! just once!
