Hi,

For the server you can use the following parameters:
/SP- /SILENT
/COMPONENTS="SuperServerComponent,ServerComponent,DevAdminComponent,ClientCo
mponent"
Optional you should add /NORESTART to prevent rebooting but you have to care
about it in your main setup.

For the client you should try:
/SP- /SILENT /COMPONENTS="ClientComponent"
With this params the gds32.dll will be installed - as far as I tested. To
prevent gds32.dll installation you have to add the "/NOGDS32" parameter.

For a list of parameters have a look at C:\<Program
Files>\Firebird\Firebird_1_5\doc\installation_readme.txt

Ciao Thomas
