This file documents the video cards SVGATextMode has been known to work
with, or not...

It also describes some known problems (some would call it "bugs"...).

Note that this report will always lag behind one version of SVGATextMode:
you'll have to find out for yourself if THIS version works for you...

--------------------------------------------------------------------------

IMPORTANT NOTE: This program WILL NOT WORK with kernels older than version
1.1.54, because they lack the "VT_RESIZE" kernel call. Compiling will also
NOT work (for the same reason). That is a problem, but you need the kernel
call to change text resolutions once the kernel has booted.

It is possible to use SVGATextMode with an older kernel, but ONLY to IMPROVE
a text mode, and NOT to CHANGE it. If you booted in 132x43 for example, you
might still use SVGATextMode to improve it (higher refresh, more detailed
font, ...). See the INSTALL file for more information !

DOS-emulator users! There seems to be a problem for SOME Cirrus Logic cards
using the DOS emulator. When switching back to a linux console, the screen
goes completely out of sync. A solution is being searched for.


--------------------------------------------------------------------------





The following cards seem to work fine. If your card is NOT listed here, but
it is listed in the chipset-strings, it probably means that it is UNTESTED!
If it works for you, please let me know (at kmg@barco.be), with a short
description of your card.


- S3 86C805, 2MB DRAM, VLB bus, Avasem/Chrontel AV9194-07 clock chip
  Product name : "VGA-805-V"
  Max clock: 70 MHz without any artefacts,
             80 MHz with temporary garbage while scrolling,
             above that, weird "fading letters" on screen.
  reported by: kmg@barco.be
             
- S3 86C805p, 1MB DRAM, VLB bus, GenDAC (RAMDAC with integrated clock chip)
  Product name : ExpertColor DSP3805A
  Max clock: 75 MHz, above that: usable, but a bit of garbage when scrolling
  reported by: kmg@barco.be
  NOTE: needs the "chipset s3gendac" line in TextConfig
             
- S3 86C964, 2MB VRAM, VLB bus, ICD2061 clock chip
  Product name : "Diamond Stealth 64"
  Max clock: tested up to 90 MHz, looks OK
  reported by: kmg@barco.be (Thanks to Kris.Coryn@p13.f1906.n291.z2.fidonet.org for providing the card)
  NOTE: needs external clock program for ICD2061 chip (should be included in "diamond" directory)
             
- Trident 8900C, 512 kb DRAM, ISA bus
  Product name: ?
  Max clock: 45 MHz.
             above that, a complete mess...
  reported by: kmg@barco.be
  
             
- Cirrus Logic CLGD5428, 1Mb DRAM, VLB bus
  Product name: ?
  Max clock: 56 MHz.
  reported by: wpg@sebb.bel.alcatel.be
  
- ET4000 W32i, 2 MB DRAM, VLB bus
  Product name: ?
  Max Clock: no limits!
  reported by: Kris.Coryn@p13.f1906.n291.z2.fidonet.org
               gesquiel@sebb.bel.alcatel.be

- Trident 8900CL, 1MB DRAM, ISA bus
  Product name: ?
  Max clock: 45 MHz.
             above that, a complete mess...
  reported by: kmg@barco.be

- WDC90C33, 1MB DRAM, VLB bus
  Product name: Western Digital ?
  Max clock: they all seem to work.
  reported by: Hans.Saelens@p16.f1906.n291.z2.fidonet.org

- ET4000 W32p, PCI bus
  Product name: "STB LightSpeed"
  reported by: root@eek.student.cwru.edu
               dmm0t@rincewind.mech.virginia.edu

- ATI VGA Wonder XL, 1MB DRAM, ISA bus
  Product name : "ATI VGA Wonder XL"
  Max clock: ~60 MHZ
             Above that, lots of garbage...
  reported by: kmg@barco.be (Thanks (again) to Kris.Coryn@p13.f1906.n291.z2.fidonet.org for providing the card)
  NOTE: since this card can already use 64 clocks of its own, this program can select between 128 (!!) different clocks.

- WinFast S400 PCI S3-964, Phoenix BIOS
  reported by: cwtong@se.cuhk.hk
  NOTE: It could be that SVGATextMode caused some PERMANENT damage to this video card. The owner reported that his CGA modes 
        had some red pixels in them that wouldn't go away (forever) after he tried SVGATextMode.
        YOU HAVE BEEN WARNED. It is not CERTAIN that SVGATextMode caused this, but is sure is a dangerous coincidence.
  NOTE2: going back to DOS gives weird screen. Need to do a power-cylce to restore this. Help is underway.
         version 0.4 might (or might not) solve this.

- ISA Trident 8800CS, 512 kb DRAM
  Product name: ?
  Clocks: 25.1 28 40 MHz
          all of them work.
  reported by: rubini@ipvvis.unipv.it

  reported by: kjahds@kjahds.com

But the following cards DON'T work... yet! :

- ANY unsupported card NOT using one of the listed chipsets, of course.
  (e.g. Matrox, OTI, Compaq, NCR, Headland Technologies, MX, Advance Logic, AGX, ...)

- ATI VGA Wonder older than V4 (i.e. V3). I could do this if someone asks me to...

- #9GXE64-Pro using "Ti3025" clock chip.
