Question about grub.conf


I have two Fedora Core 6 systems. On one, the boot entry looks like:

title Fedora Core (2.6.22.9-61.fc6)
root (hd1,0)
kernel /vmlinuz-2.6.22.9-61.fc6 ro root=LABEL=/ vga=791
initrd /initrd-2.6.22.9-61.fc6.img

On the other one, it looks like this:

title Fedora Core (2.6.20-1.3002.fc6xen)
root (hd0,0)
kernel /xen.gz-2.6.20-1.3002.fc6
module /vmlinuz-2.6.20-1.3002.fc6xen ro root=/dev/VG0/LV00 vga=791
module /initrd-2.6.20-1.3002.fc6xen.img

Why the difference? in one there is a "kernel" entry and an "initrd" entry. In the other, there is a "kernel" entry and two "module" entries...

In the second one, the "vga=791" entry doesn't seem to work. Could I convert the second one to:

title Fedora Core (2.6.20-1.3002.fc6xen)
root (hd0,0)
kernel /vmlinuz-2.6.20-1.3002.fc6xen ro root=/dev/VG0/LV00 vga=791
initrd /initrd-2.6.20-1.3002.fc6xen.img

and will it work correctly???

Thanks

Harold

I say that is a better choice. Now for the vga line it depends if the kernel has Console display driver support, boot logo, and a frame buffer that the video card supports out of the kernel. If the other works then the framebuffer exist for it but the kernel itself may be missing the other two options enabled. Now all those features are built into the kernel so I know of no way to check for that. Now there maybe a config file in /boot that has the same kernel verson number. That may tell you what the kernel is built too. Other option is get the matching src.rpm kernel file and check out the config and spec file in it.
