Just to share my experience making my Lenovo ThinkPad T61 to work:
The issue was not showing the graphic mode, just blank screen after text mode messages.
I was able to see the graphic mode on the external 4x3 17" monitor.
From Windows, I found out that the native screen resolution is 1440 x 900
After pressing escape at the grub4dos boot countdown screen I was able to edit options and add "vga=ask"
The option for 1440x900x32 was (hexadecimal) "365" and converted to decimal is 869.
The interesting part is if I've used vga=869, or vga=0x365, I got nothing after running the splash screen.
To reboot properly you can use "alt-F1" and there type "reboot"
so my permanent solution was:
Boot Windows, navigate to c:\RemixOS
edit meny.lst to look like this (I've used Notepad++):
----------------------------------------------------------------------------------------------
default 0
timeout 10
title Resident mode - All your data and apps are saved
find --set-root /RemixOS/kernel
kernel /RemixOS/kernel root=/dev/ram0 androidboot.hardware=remix_x86_64 androidboot.selinux=permissive quiet SRC=RemixOS/ DATA= CREATE_DATA_IMG=1 vga=ask
initrd /RemixOS/initrd.img
boot
---------------------------------------------------------------------------------------------
I hope this will help someone.
