hi;
Being new to linux myself (definitely the blind leading the blind) -
I've been reading along these various linux NGs over the last couple of
weeks, and it seems GRUB info can be found in /boot/grub/grub.conf and
/boot/grub/menu.lst (<--that's an "L" = menu.LST)
also perhaps booting to Knoppix (or similar) LiveCD, you can access
this info (you sure can't from XP, unless the partition/s are FAT32) -
perhaps the command from a console can be useful that others here can
use to help diagnose the situation as well.
hdparm -l
or
hdparm -i
or some combination thereof (from a Knoppix boot, you may need to
prefix the above with 'sudo' when using the konsole (in KDE)
sudo hdparm -i
....also info can be found using the cat command;
# cat /proc/devices
....i snipped info this below from a thread in a NGs search;
show io port address cat /proc/ioports
show pci info cat /proc/pci
show block devices cat /proc/devices
show dma por cat /proc/dma
show eth0 bytes cat /proc/net/dev
show file system support cat /proc/filesystems
show interrupts cat /proc/interrupts
show ip forwarding (1) cat /proc/sys/net/ipv4/ip_forward
There are other ways, and the GRUB info should be priority I
guess...Others will show up and clarify hopefully - (*hint* - being
lazy is not going to get you much help ;-)). Just trying to help
.
