Quite interesting, as I occassionally have short "drumbeat" on the PC speaker. It is like \e[10;x]\e[11;15], but seems irreproducible to me with any particular x. I do not suspect overheating, as the BIOS hardware monitor has shown 51 deg Celsius after some hours running for over two years now. > Maybe ACPI could report thermal zone as well, try looking at > /proc/acpi/thermal_zone/* tree. MB is EliteGroup L7S7A2, CPU is AMD Athlon XP 2000+, and /proc/acpi/thermal_zone/ is empty. LM chip is a LM78, but lmsensors outputs only rubbish data.
