    ASUS P4PE Motherboard (BIOSrev 1002)
    Intel Pentium 4 2.4Ghz
    LeadTek Ultra 250 TD Geforce4 Ti4600

    CPUTYPE=p4 in /etc/make.conf

    Relevant kernel compilation options:

        options     VESA
        options     SC_PIXEL_MODE

    dmesg output:
        VESA: v3.0, 131072k memory, flags:0x1, mode table:0xc03f2ac2 (1000022)
        VESA: WinFast VGA BIOS.

>Description:
        Using vidcontrol(1) to change the video mode to most modes past
	80x50 locks up the machine solid, sometimes rebooting, sometimes
	locking up with a beep. No panics occur. The same hardware on
	Linux 2.4.20 does not exhibit this problem, and handles the extended
	modes without an issue. The problem is experienced with and without
	the NVIDIA accelerated display drivers.
>How-To-Repeat:
	$ vidcontrol 132x50
>Fix:
