CentOS - May 2016 - Successful update from CentOS 6.7 to CentOS 6.8, but ...

Hello,

I have several CentOS 6 VMs, I have updated the first one successfully,
but there is one thing I miss or I don't like;

How do I get the standard console with 80x25 back?

this is /boot/grub/grub.conf


default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.32-642.el6.x86_64)
	root (hd0,0)
	kernel /vmlinuz-2.6.32-642.el6.x86_64 ro
root=UUID=a27dc9a0-ea3a-497d-a9c3-80c7bbba31fa rd_NO_LUKS
LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto
rd_NO_DM rd_NO_LVM  KEYBOARDTYPE=pc KEYTABLE=de config_NO_HZ vga=0x0300
	initrd /initramfs-2.6.32-642.el6.x86_64.img


I've added 'vga=0x0300' (the same would be 'vga=768'), but
this
results in 100x37?

Thanks for Help,
Walter
