INT 0eH is a hardware-generated interrupt (IRQ 6) forced by the floppy
disk controller.

The ROM-BIOS code sets bit 7 in the BIOS "seek_status" variable (0040:3e)
which indicates that a diskette seek is in progress.  This flag is used by
INT 13H to determine if a diskette controller recalibration is required
before the next action.

  CPU Exception Interrupt  
286+ computer execute INT 0eH when the CPU is in protected mode and it
detects access to a page or memory which has been swapped out to disk.

Protected-mode operating systems watch for this and read the data back
into memory and handle the needs of virtual memory management.
