When you use the suggested configuration for grub from the documentation you will not be able to boot gentoo if you don't have a graphics card installed in the machine. The offending line of configuration is splashimage=(hd0,0)/grub/splash.xpm.gz if you have splashimage defined, grub will lock-up and fail to boot. I've not seen what grub produces as I do not have a nullmodem cable to use with a serial line. Reproducible: Always Steps to Reproduce: 1. Install gentoo using the default suggested configuration from the handbook. 2. Remove graphics card. 3. Boot Actual Results: Linux fails to boot succesfully, probably locks with an error from grub. Expected Results: Booted into linux login. The solution was to remove splashimage=(hd0,0)/grub/splash.xpm.gz from grub.conf in /etc/boot/grub/
This is a candidate for a Tips 'n Tricks document. Depending on #44335
Thanks for reporting. I've added a comment about this in the example grub.conf.
