  Sorry, I can't find the manufactor this old 75MHZ mainboard,
the manual say it's 'VIA Apollo VPX' motherboard.
  CPU : intel mmx 233
  HD : segate 3.2G
  OS : Win98 + dos6.22

 Normally it squealed for 10 secs or more,(I reset the machine), but sometimes
it squealed for serval secs then stoped. It squealed just when Os check hardware
during the installation of win98 and when I edit hard disk partition.
