In Microsoft Windows 95 the default "compatibility" display resolution was 640x480 using VESA standards. Later in Windows 98 the new lowest default was 800x600 using VESA standards. These "safe mode" display resolutions were a fallback if no video driver specific for the system video adapter was installed. These are the best known VESA display standards. See also [[Legacy PC Display Standards]].In Windows NT, Windows 2000, Windows XP or Windows Server 2003 display properties:*Select Display Adapters from the Select Hardware Type dialog box.*Select Standard Display Adapter (VGA) from the device list, then click OK.

It can drive most VESA-compatible video cards, but only makes use of the basic standard VESA core that is common to these cards. The driver supports depths 8, 15 16 and 24.The default graphics driver is vesa (package xf86-video-vesa), which handles a large number of chipsets but does not include any 2D or 3D acceleration. If a better driver cannot be found or fails to load, Xorg will fall back to vesa. Here is an example for a GRUB stanza, I grabbed out of my /boot/grub/menu.lst": title Debian GNU/Linux, kernel 2.6.18-4-k7 root (hd0,0) kernel /vmlinuz-2.6.18-4-k7 root=/dev/hde2 ro vga=791 initrd /initrd.img-2.6.18-4-k7You could also have it look like this: title Debian GNU/Linux, kernel 2.6.18-4-k7 root (hd0,0) kernel /vmlinuz-2.6.18-4-k7 root=/dev/hde2 ro vga=0x317 initrd /initrd.img-2.6.18-4-k7== VESA video modes in MSDOS ==MS-DOS VESA mode selection was well known to PC gamers back in the early 1990's. Most PC games of the day ran in DOS mode. These games largely did not support the vast array of proprietary video drivers available with some exceptions. The VESA mode drivers allowed gamers to display the best possible resolution and color depth for a wide array of video cards. Game developers were able to simply video card support by using VESA standards.Color depth of up to 24-bit are possible using DOS Super VGA VESA standard modes in MS-DOS. Most of the modern videocards comes with a VBE2-Bios or a VBE3-Bios and with an own modetable of vbe modenumbers maybe with a resolutions up to 2048x1536 pixel and with 8, 15 or 16, 24 or 32 bits per pixel and with a aspect ratio of 4:3, 4:5, 16:9 and 16x10.SuperVGA programming uses screen data that can exceed 1 MB in size. However, the normal VGA card only offers a 64k memory access at A000h (some cards provide 128k). [[Category:Computer Technology]]
