Hi there,
   
  I am new to FreeBSD and trying to install a fresh FreeBSD OS to my computer. However, I am getting BTX error as below: 
   
  Building the boot loader arguments
Looking up /BOOT/LOADER.. Found
relocating the loader and the BTX
Starting the BTX loader
  BTX loader 1.00 BTX version is 1.01

BTX halted
   
  I have verified my CD built from iso image (tried both i386 and AMD64 ) and could not figure out what the problem is. I have also disable all unrelated BIOS setting but still no luck. Hope someone will be able to help out.
   
  FYI, my system is: 
  Processor: AMD Athlon 64 X2 Dual Core Processor 4000+
Memory: 1GB, Single Channel, 64-Bit, 2T
Main Board: Abit NF-M2P
  Bios: v6.00PG
NVMM: 4.071.0302/02/07
  80GB Hard-drive.
   
  Thanks.
   
  Regards,
  Felix

I was having this issue too a while back.  I replaced the CD-ROM with a new CD-ROM/DVD drive and now it works ok.
