J,
Yes, I agree, but one location is still better than 1000. I have bitched about "making it right and still screwing up" to Philips. Maybe ESA can add a "boot vector hunter" to FlashMagic so we can recover those few unfortunate chips.

J,
It is sad that customer support for virtually all companies has become a cost center rather than a sales support center. I called the second largest hardware chain in the USA (Lowes) with a simple question on one of their products and the reply were "I don't know, you will have to figure it out"

Philips does have a few guys that are fighting for us, more power to them.

I have finally succeded in making a boot method without switches for the P89C51Rx2, using FlashMagic.

Le me know a few more details about your bootloader, if it fulfills a need here (erikm@digrec.com) I may suggest the company contact you.

Have fun,

Erik
