15. Notes on using Laptops and CardBus 

 
The HDSP system uses the notebook’s PCMCIA type II port as 

CardBus

 interface. Compared 

to a PC-Card, which only has access to the outdated ISA-bus, CardBus is a 32 bit PCI 
interface. When inserting the CardBus card it usually is detected automatically by the notebook 
hardware and then by the MacOS. An icon labeled 'Hammerfall DSP' will appear on the 
desktop. 
 
Like with a desktop computer it is not possible to remove a PCI device while in operation. First 
the operating system has to receive a 'removal request’, then the device has to be stopped. 
 
This procedure prooves to be very simple on the MacOS: just drag the 
'Hammerfall DSP' icon in the trash can. The MacOS internally de-installs 
the CardBus card and switches off power (the red Host LED begins to 
blink). The card can now be pulled out of the PCMCIA slot. 
 
The Hammerfall DSP System was tested thoroughly on several notebooks by RME. We did not 
find any compatibility problems with older G3 Powerbooks or the latest Titanium. The 
performance was good and allowed to use latencies down to 1.5 ms. 
 
The mobile operation of the HDSP system can cause problems. Explanations and solutions on 
digital noise, ground loops, headphone operation and Line Out wiring, power supplies and the 
mobile operation with battery can be found in the Tech Info

. Although this Tech Info 

speaks about IBM-compatible machines it is still interesting even for the MacOS user.
