I am looking for gxt130p driver for aix 4.2.1. Where I�ll can find it?
AIX 4.2.1 is no longer supported, therefore you won't get it from IBM. If you have original 4.2.1-CDs (unlikely) it would reside on the "additional software" part, IIRC disk3 and 4.
I'd suggest you upgrade AIX 5.x or 4.3.3 if your software requires AIX 4. (POWER3 is no longer in 5.3. If your machine is f.i. a 43P you could install only 5.2 or 5.1.) In any case it would be easier to get the required driver for one of these versions than for the (already 8 year old) 4.2.1.
The driver is contained in the package PEX_PHIGS.dev.pci.1410b800, which you could install in base level from your CDs and download from the IBM site as an update version (the base level is required to be installed).
Have a look in the AIX part of this forum for the URL of the download site.
Hope this helps.
