I'm setting up this new pc and used Lilo as the bootloader, first time I use Lilo. I used a rather standard kernel from gentoo-sources, only disabling what I was sure I'd could miss intel cpu stuff as this is an AMD machine, wireless, ... and add a few thing I knew I'd need like JFS, WFS, Areca raid card and RME soundcard.

But the strange thing happens on boot. I get a screen with a red rectangle "GNU/Linux - LILO 24 - Boot Menu" and it directly shows below it:

Code:

boot:
Loading gentoo.....................................................
..........................................................................
...................................
BIOS data check succesfull


This check takes about 2-3 minutes which seems excessive. Once it passed it flies though the boot and ends at the login prompt.

I'd like to get rid of this but I have no idea where to look. The questions I have so far:

- I expect Lilo to wait for a timeout so you can select which kernel to start. This timeout is set at 30 seconds in the config but it starts directly with the only entry "gentoo". Is this because there is only a single entry?

- is this BIOS check coming from Lilo? If so, how do I deactivate it?

- I saw in the kernel config that "NSA SEL Linux" option is set. Could this be the one doing this check?

I had to check the date of the post. Lilo is not a name I've heard in a long time.

The bios check is something printed by lilo. Here is a part of the manual.
Quote:
The options described here may be specified at boot time on the command line
when a kernel image is booted. These options are processed by LILO, and are
removed from the command line before it is passed to the kernel, unless otherwise
noted.

...

nobd
Suppresses the BIOS data check. This option is reserved for use with
non-IBM-compliant BIOS's which hang with the lines:

Loading...............
BIOS data check

So try adding "nobd" to the kernel command line.

Lilo is so old it's legacy boot only. I don't know what that bios check is but on a modern system the UEFI comparability emulation of it could be slow.

It may be it is not the BIOS check that takes all the time, it may be merely the message left on the screen while Lilo is collecting pieces of kernel from hard drive to load it. Do you see the HDD activity light on when it happens?

Since it printed "succesfull" after the check this looks like a better explanation.

@Spanik are you switching to lilo because grub1 was sunset?

Check your dmesg. This sounds more like something in the kernel delayed fbcon initialisation.

You could say I'm a tradidionalist :D I prefer Grub but can't get along with Grub2. I'll try the option nobd. The MB is in legacy mode, could be a lot slower indeed. Thanks for that.

There is no HD activity. The /boot is on a sata SSD and the rest of the OS is on a NVME-M.2 stick. Could be the NVME doesn't make the hd light go? This board is new to me, not very far yet in the install.
