 Hi,
 
 just a short Update on this:
 
 - Commenting out the two last lines of ata_ahca_dmainit (and also the 
 definition of ctlr; the Compiler wasn't amused on unused local 
 Variables) in ata-chipset.c does seem to correctly circumvent the 
 Problem; I was able to boot w/o the "hw.physmem" Parameter and a 
 buildworld/-kernel and install of both worked fine.
 
 - ASRock sent me a new BIOS; however, that made FreeBSD (and Linux) only 
 "see" 3.5G of the installed 4G RAM. ASRock stated that more memory is 
 only supported for Windows_64. Of course there were no DMA issues with 
 only 3.5G visible.
 
 - Wasn't able yet to get more Info re. the BIOS-Patch that was applied 
 by ASUS :-( Still trying.
 
 Cheers,
 _ralf_
