id summary reporter owner description type status priority milestone component version resolution keywords cc 166 Reference old ticket #61 Chuck McKinnis pasha I see ticket #61 is closed. Nothing I was told to try worked. I have tried EVERY combination of switch there is. 2.22 works fine with /acpi /smp /tmr , but no later version. Board is Asus A8N-E amd dual core. IDA, Adaptec 7870. Boot with Altf2 stops loading HPFS OR JFS whichever is first in config.sys. I am happy running 2.22 but wanted to let you know the problem still exist. Ticket #61 has photos and log files which may help. Ben defect closed major ACPI PSD 3.05 wontfix
