Asus P4B266-E and P4S333 in the test: Intel 850 versus Intel 845 and SiS 645

Asus P4B266-E and P4S333 in the test: Intel 850 versus Intel 845 and SiS 645

The P4S333

Scope of delivery and documentation

The scope of delivery of the P4S333 is of course lower than that of the P4B266-E due to its different positioning on the market. The P4S333 “only” includes the following components:

  • P4S333
  • P4S333 Support CD (Rev. 25.03)
  • USB 1.1 module
  • COM2 port
  • ATX slot bracket
  • An Ultra ATA/100/66/33 IDE cable
  • An ATA/33 IDE cable
  • A floppy cable
  • Three additional jumpers
  • English manual (User Guide)
  • 'Quick Setup Guide' and 'Reference Card'
  • 'Jumper and Connector “Sticker

P4S333 additions

We can only repeat ourselves with the manual. Also kept entirely in English, it corresponds to the high quality of the P4B266-E manual.

The “Quick Setup Guide” also only differs from its P4B266-E counterpart in the point “Scope of delivery”, so we here also refer to the section above and do not go into all of the content again. The same applies to the 'Quick Reference Card' and the 'Jumper and Connector Sticker'. They are merely adapted to the design of the P4S333, but otherwise serve the same purpose.
