I have solved the burning bugs and it appears the problems were to do with running Windows XP and using the "Windows API" option in IC-Prog instead of "Direct IO".
By running a utility called "totalio.sys," (in directio.zip) all applications get full control of the I/O ports and thus IC-Prog works perfectly under Windows XP and Windows 2000, since the IC-Prog driver that is available doesn't work for XP.
How To Use IC-Prog with Widows XP/NT/2000:
You can download a driver for IC-Prog from their website - it is called "icprog.sys" but it is really just a renamed driver originally called "giveio.sys". This utility was written by Dale Roberts as one of a set of utilities to give applications under NT more control over the I/O ports. Clicking on the "Enable NT/2000/XP Driver" check box in the settings will try to install this "icprog.sys". Under XP, it installs but can't be started.
The purpose of this driver is to give an application access to the I/O port but only through the driver. This is because XP, like 2000 and NT, doesn't let you have full access to I/O ports like in 95/98/MS-DOS.
However, there is another way. By using another utility, called "totalio.sys", ALL applications can have full control over the I/O ports, and not through a driver's interface. This means you can let IC-Prog use "Direct I/O" instead of "Windows API (in the "Interface" group of hardware settings) and ignore the "Enable NT/2000/XP Driver" option completely. "totalio.sys" (in theory) should also let any programs which control ports directly to work under XP.
Installing "totalio.sys":
Extract "totalio.sys" from the "directio.zip" file to "C:\Windows\system32\drivers" directory (or equivalent).
Extract "loaddrv.exe" from the "loaddrv.zip" file and run it.
In the edit box, type in the full path to "totalio.sys" eg. "C:\windows\system32\drivers\totalio.sys"
Click "Install".
Click "Start".
Click "OK".
The driver should now be running. You can check this by running "Start->Programs->
Accessories->System Tools->System Information", then clicking on the tree item "System Information->Software Environment->Drivers" and looking for "totalio" in the view on the right.
To start or stop the driver after it has been installed, you could use the "loaddrv.exe" program, or use the following commands in a command prompt:
"net start totalio" to start the driver.
"net stop totalio" to stop the driver.
You could put this in a batch file in the IC-Prog directory, eg.
@echo off
net start totalio
icprog
net stop totalio
You can configure the driver to run automatically on startup, but I wouldn't recommend it. You can do this via Device Manager, select "View->Show hidden devices" and look under "Non-Plug and Play Drivers" to find "totalio", look at its properties, and change the startup type from "Demand" to "Automatic" (NOT "Boot" or "System") in the "Driver" tab.
The batch file concept is safest, as you only run the driver when you need to and unload it when you don't need it.
How to configure IC-Prog:
Goto: Settings->Options->Misc. Tab
Uncheck "Enable NT/2000/XP Driver"
Uncheck "Enable Vcc control for JDM" (the help file says it is experimental and not to use it).
Select "Realtime" in the "Process Priority" group. (in theory, this will prevent other CPU-intensive applications from interrupting your burn process).
Goto: Settings->Hardware
Select "JDM Programmer" from "Programmer" dropdown list.
Select "Direct I/O" from "Interface" group.
Uncheck all the check boxes under "Communication".
Select correct COM port.
Move the "I/O Delay" slider to 10. (other values gave errors for me, but this value could be specific to the PC's CPU speed - tweak until you get no read/write errors).
