EPROM Updates Hammerfall Series
EPROM Updates for revision 1.1 boards
In the first months of 'Project Hammerfall' and 'Hammerfall
Light' production several improvements were implemented into the hardware.
The hardware definition is stored in a non-soldered EPROM. This allows a
simple update of the hardware by exchanging the EPROM.
* These three items affect only a very small number of the earliest cards.
When do you need an EPROM update?
First of all please check if your Hammerfall is a hardware revision 1.1 (see below.) If so all of the above is already fixed, in case the EPROM is labeled 'W52' (for Windows 9652) or 'W36' (for Windows 9636.) This version was shipped since early 2000. As long as the software Gigasampler/Gigastudio (GigaX) of Nemesys isn't used no further EPROM update is necessary.
Since driver version 2.51 the Hammerfall supports
Gigasampler and Gigastudio using the GSIF interface. Note that all Hammerfalls
of hardware version 1.1 need an EPROM update for this. The new EPROMs are
labeled 'W52_G' or 'W36_G'. Without this update playback is interrupted
in GigaX operation.
How to identify revision 1.1 boards
The hardware revision 1.1 can be identified by:
The final EPROM of revision 1.1 can be recognized by a label showing 'W52_G' (for Windows 9652) or 'W36_G' (for Windows 9636.) All other marks (for example 9652) or a missing label indicate an older hardware version.
Removing the EPROM is complicated and needs a special tool. We therefore recommend to let your local dealer do the update. The final EPROM is only available at your local dealer/distributor.
EPROM Update for revision 1.5/1.6 boards
The hardware revision 1.5 can be identified by:
Since June 2000 hardware revision 1.5/1.6 is shipping. These cards are already equipped with the final EPROM version including GigaX support. The cards shipped as Mac version also use board revision 1.5.
