Hi Jérôme, > could someone check if "Core" and "Core 2" cpus are well identified in > Pulse ? If not, be sure to provide the usual sysinfo output. I missed the chance to do that. I needed to replace the ATA drive by a SATA drive in order work around the very poor harddisk performance in ZETA. On SATA, Haiku won't boot anymore (on the plus side, ZETA performs as expected now). Hopefully, this situation could be improved shortly? :-) Best regards, -Stephan
