On my system, interrupt calls to the BIOS aren't possible, but there are ways to get information about the BIOS. Here's a script that I use to get BIOS and boot info. It requires Parse::DMIDecode and Linux::Bootloader.

#!/usr/bin/perl 

use strict;
use warnings;
use Parse::DMIDecode qw(@TYPES %GROUPS);
use Data::Dumper::Concise;
use Linux::Bootloader;

my $dmi = Parse::DMIDecode->new(
          dmidecode  => "/usr/sbin/dmidecode",
          nowarnings => 1,
);
$dmi->probe; 

print $dmi->keyword("bios-address"), "\n",
      Dumper($dmi->keyword("bios-characteristics")), "\n",
      Dumper($dmi->keyword("bios-currently-installed-language")), "\n"
+,
      Dumper($dmi->keyword("bios-installable-languages")), "\n",
      $dmi->keyword("bios-release-date"), "\n",
      $dmi->keyword("bios-rom-size"), "\n",
      $dmi->keyword("bios-runtime-size"), "\n",
      $dmi->keyword("bios-vendor"), "\n",
      $dmi->keyword("bios-version"), "\n";

my $bootloader  = new Linux::Bootloader();
my $config_file = '/boot/grub/grub.conf';
$bootloader->read($config_file);
$bootloader->print_info('all');
