I noticed a strange behaviour with one of my 486 boards (after I repaired the PC speaker - resoldered the cables). Its a UMC based 486 PCI board. The pc speaker beeps very often when I press a keyboard button to long or accidentically press two keys at the same time. I doesn't happen allways but frequently.
System uses AMD 486DX4-100 and 24MB Ram.
Phoenix Bios
Testing various bios settings didn't change anything. Happens in bios, in freedos & MS-Dos, so it doesn't seem to be driver or OS related.
Any suggestions what the reason for this could be?
Apart of the frequent "beeps" the system seems to work flawlessly.
