Dear all,

I noticed that since using the xt ide bios following thing occurs:

- during boot up hdd detection, my WDC is like spinning on and off 3x
- same happens when shutting down w95
- same happens when testing dma speed (yes strange example)
- besides that operation is fully normal
- this only applies to my WDC 80gb hdd, this won’t happen on a 420mb hdd, 300gb maxtor

Do you have any clue? I have the slight feeling that these events won’t prolong lifetime of that hdd 😉

Thanks

I have not seen that. Perhaps the landing zone detected incorrectly?

I put following numbers for lzone:
- cylinders
- cylinders-1
- 0

Unfortunately no change in behavior. Strange thing

Seems like a problem I had as well. See here for a solution I received: https://forum.vcfed.org/index.php?threads/xti … 34#post-1305261.

I needed to make a custom XTIDE build and remove MODULE_POWER_MANAGEMENT. I also removed MODULE_SERIAL, MODULE_SERIAL_FLOPPY and MODULE_WIN9X_CMOS_HACK as I didn't need it for my 386DX. After that the problem was resolved and it booted a hell of a lot faster as well.

This is bang on. There is a known issue with MODULE_POWER_MANAGEMENT. Build it without that module and you will be fine.

Seems few people notice this since everyone is using solid state BS these days...

BS means "Blazingly-fast Storage" no doubt!

Wow great. That’s it. Thanks a lot. I mean I would assume that a 80gb drive is well aware of PM but your symptoms are identical. Damn that I am not owner of my eprom burner anymore 🙁((

It's a bug in the XUB. The drive being aware of power management is what makes it susceptible to the bug.

Ok understood. Also found the instruction for custom builds - just have to organize a burner again.

If anyone has an idea of how to deactivate the win95 shut down hdd-handling (power mgmt function / or parking) -> very welcome. Could maybe be a a registry hack but I couldn’t google anything
