The vulom can be flashed via VME-bus from the RIO by using the binaries located here:
/nfs/groups/daq/usr/kurz/gsi_vme/flash/vulom/

There are subdirectories for several platforms, like
RIO4_Linux_2.6.33 (this is for our linux-RIOs)
RIO4_Linux_2.6
RIO4_Lynx
RIO3_...
IPV_...

IFC will follow soon...

The binaries needed for flashing are the following:

eraseflash <add> <slot>              
progflash  <add> <slot> <bitfile>
veriflash  <add> <slot> <bitfile>
restart    <add> <slot>

When invoked in the above order, things should work.
For 2.6.33 there are ALIASes:
vulom_erase
vulom_flash
vulom_verify
vulom_reset


The bitfiles for vulom4b are located here:

/nfs/groups/daq/usr/kurz/gsi_vme/flash/vulom/bitfiles/
