Now I'm really short in time, so very minimalist: Mobo: ASUS M2A-VM HDMI, a while ago the BIOS was up-to-date, I guess it's still up-to-date Integrated graphics ATI Radeon X1250-based replaced by a NVIDI Geforce 7200GS. # hwinfo --cpu 01: None 00.0: 10103 CPU [Created at cpu.301] Unique ID: rdCR.j8NaKXDZtZ6 Hardware Class: cpu Arch: X86-64 Vendor: "AuthenticAMD" Model: 15.107.2 "AMD Athlon(tm) X2 Dual Core Processor BE-2350" Features: fpu,vme,de,pse,tsc,msr,pae,mce,cx8,apic,sep,mtrr,pge,mca,cmov,pat,pse36,clflush,mmx,fxsr,sse,sse2,ht,syscall,nx,mmxext,fxsr_opt,rdtscp,lm,3dnowext,3dnow,rep_good,extd_apicid,pni,cx16,lahf_lm,cmp_legacy,svm,extapic,cr8_legacy,3dnowprefetch Clock: 2100 MHz BogoMips: 4199.32 Cache: 512 kb Units/Processor: 2 RAM: 2GB Sound cards: 2x Terratec EWX 24/96 just stereo IOs, Envy24, not as one virtual card, I'm only using one card at the moment Not connected anymore: Swissonic USB MIDI IO No USB devices, e.g. keyboard and mouse are PS/2. I'm connecting MIDI in the Qtractor (quasi QjackCtl) ALSA MIDI tab. To be continued tomorrow or on Friday. Thank you! Cheers!
