Issuing BIOS interrupts in Linux

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?

TIA,

Rajat
