Changes in 0.12

• Applied Jean-Michel's G550 patch

Changes in 0.11

• Dualhead support for the G450 (NOTE: no TVout though....)

Changes in 0.10b

• Clears ZORG on G450, this fixes blitting crash (no reboot from win required)

Changes in 0.10a

• (whistles)....This release never happened:-)

Changes in 0.10

• TVout support (for medium resolution modes - picture placement still off)
• G450 support (must reboot from windows to prevent crash in screen to screen blit)
• Adjusted G100/G200 to use bios initialisation (colours still broken...)

Changes in 0.09(a)

• 0.09 was initially (well for 3 months!) released with singlehead broken...
• Fixed G400 crash when cold booting (no idea why it works, but it does...)
• Preliminary G100 support (you must reboot from another OS, as with G200 - also only 32-bit)

Changes in 0.08

• Preliminary G200 support
• Removed DMA stuff (just wastes memory ATM)
• More sensible use of CRTC/DAC connection on dualhead
• MAVEN border is black!

Changes in 0.07

• PCI retries re-enabled (did not fix problem)
• DualHead support
• DMA preliminaries(just wastes 1MB RAM ATM)

Changes in 0.06

• Supports custom monitor timing
• PCI retries disabled
• Detects amount of card RAM
• SDRAM support
• Uses VBI instead of VSYNC interrupt (more blanking time after waiting for retrace)
• CRTC unlocked at init

Changes in 0.05

• Refresh rate set much more accurately.
• H-Sync, V-Sync polarity is REALLY set!
• Fix for R4.5.0 implemented, but still best to upgrade.
• Memory priority requests are set
• Benaphore for engine synchronisation initialised properly
• Synchronisation now always waits for idle if it has to wait, rather than attempting (and sometimes failing) to wait for individual operations.
• Pixel clock of display mode reported accurately (so refresh rate reported correctly)
• Maximum pixel clock reported correctly

Changes in 0.04

• Discovered driver only works with R4.5.2, no fix (yet?) (please upgrade)
• Removed MAX hack (problem was not with MAX cards, but with Be version - see above)
• Adjusted vertical sync to give more precise refresh rates (still could be better)
• Fixed bug with MOVE_DISPLAY (occurred when returning from fullscreen apps)
• Adjusted mouse pointer positioning, so hot spot is in the correct place.

Changes in 0.03a

• Reworked interrupt code, now uses correct method.

Changes in 0.03

• Vertical blank interrupt fixed - no longer steals interrupts!
• Polarity is set for VSYNC and HSYNC
• refresh with low dot clock is now correct
• logfile now has 3 levels (1 - all, 2 - info, 3 - error)
• ROM is now mapped in a better way (thanx for the info)
• Sounds like init is failing for some G400MAX owners. Please try new version first, but if it still fails please do the following (it sets it up as a standard G400 without using the BIOS):
  • cd accelerent/mgag400
  • mv mga_fake_info.c mga_info.c
