IBM 300GL - 6282

Post by omarsis81 » Mon 15 Jul, 2019 4:25 pm

I'm trying to add a new computer - IBM 300GL model 6282 - It has the 430VX chipset (already emulated) and the PC87307 Super I/O (only the PC87306 has been coded)
I tried to compile the new model using the PC87306 Super I/O but doesn't work.
When I try to run the new model the emulator quits - I searched for the pcem.log and it says "intel_flash_init on unsupported ROM set 40"
How can I have the unsupported ROM set supported?
Do you think the PC87306 and 307 are different enough to be incompatible?

The model is similar to one pictured, it has a beautiful BIOS screen and I think would be a nice addition to PCem ;)

Have a look at intel_flash.c.

No idea. Look at the datasheets.

Thank you for the quick reply Sarah!
I'm currently looking and trying to understand "pc87306.c" - I noticed that all entries with pclog are commented with a double slash. Did you forget to remove those comments? Because they are not compiled and that logging is very useful

No. How can I be sure? And if it doesn't, why do I get that error message?

Anyway, I read both PC87306 and PC87307 datasheets and they look quite different, new registers and different bit values and that's out of my range for programming
