Hi List, I want to issue BIOS interrupts in Linux (both user space & kernel space are fine). More specifically I want to issue BIOS interrupt 13h for accessing disk using the BIOS routines. How can I do so (issue the BIOS interrupt)? In the file /proc/interrupts on my system, the interrupt 13 h (19 decimal) is used by some USB driver: 16: 0 Phys-irq uhci_hcd:usb1, uhci_hcd:usb4 17: 2 Phys-irq peth0 18: 637572 Phys-irq eth1 19: 0 Phys-irq uhci_hcd:usb2 20: 1275249 Phys-irq uhci_hcd:usb3 So will I be able to use the BIOS routine in this case?
