I've been having a wierd problem with my 386 machine that I thought I'd see if anyone had seen before. After the system has been running for a while, a bad DOS command or search for a file out of the current directory will cause the system to halt and display "All data on the selected unit will be destroyed. Proceed (Y or N)?". The message comes from the BIOS prom on the hard/ flopy controller. It thinks it wants to format the hard disk. The system is a 25 MHz clone, with motherboard by PC-Calc (I think) that uses a Chips & Technologies chipset. The hard drive is a SCSI 80 Meg Seagate ST-296N with an ST-02 controller. Everything else in the system has been changed out. The OS is DOS 4.01. We have been running 4DOS (in the evaluation period), but removing it has no effect. Booting from a known "clean" (read that virus-free) floppy, with nothing in either config.sys or autoexec.bat, has no effect on the problem. We have replaced the controller card, and run with every other card in the system removed. We swapped a CGA card for the VGA card. Only the motherboard (my suspicion), the hard drive and the floppy have not been swapped out. If anyone has seen anything like this, please email to me. If interest is shown, I'll post back to this newsgroup.
