Short: A2410 ShapeShifter driver Author: Brian_King@mitel.com Uploader: Brian_King mitel com Type: misc/emu Version: 0.8 Replaces: misc/emu/a2410evd* Architecture: m68k-amigaos This is version 0.8 of A2410EVD, an External Video Driver for ShapeShifter version 3.2a or higher. It supports MMU-refresh on 68040-equipped machines, and support delta-buffer refreshing on other Amigas running ShapeShifter. Source code is now included (be aware that the asm-code is brutal looking). Installation ------------ Simply copy the A2410 file into your ShapeShifter "Video Drivers" directory. You *must* have EGS (by Viona) and the A2410EGS driver (by Juergen Schober and Thomas Herlyn) installed and working correctly. Additionally, *DO NOT* expect to run both ShapeShifter and the Workbench on the A2410, and switch between them. ShapeShifter Settings (Memory) ------------------------------ If you are using MMU refresh (with a 68040 only), you should make sure that you leave enough memory aside for the single video buffer. In other words, do not use the "Largest Free Block" setting in Shape's Memory options. Instead, make sure that your "Mac memory" suits the following approximations: Resolution Amount to subtract from "Maximum" ---------- --------------------------------------------------------------- 640x480 310K. So if "Maximum" was 5000, "Mac memory" should be 4690. 800x600 480K. 1024x768 768K. If you are using delta-buffer (with 68020 or higher), you need to DOUBLE the amounts shown above. You should try to make sure both the MacROM image AND the video-buffer for the A2410 are in 32-bit memory, otherwise performance suffers greatly. ShapeShifter Settings (Graphics) -------------------------------- Make sure that the "Color depth" option is 8-bit. "Screen type" should be "External" "External driver" should be the "A2410" file. Use the "Choose" gadget to select an A2410 screen mode, which you've already setup using Juergen's A2410Config utility. Make sure the horizontal size is a multiple of 32, since I don't do it yet. Set the "Refresh rate" to around 10 on an 030 machine, or 5 on an 040 machine. The "MMU refresh" check-box within ShapeShifter has no effect on the external driver. Instead, once the driver starts, it will provide you with some choices... Distribution and Copyright Notice --------------------------------- A2410EVD is giftware.
