Ugh, no! How can we expect the user compiling a kernel to be *so* familiar with address space re-mapping / BIOSen (_his_ particular BIOS, specifically, and what / how it re-maps memory) / etc to be able to answer such questions? "Select ... if you have ... RAM installed" is perfectly clear, simple, and all that's needed. BTW, just imagine what a user would need to do to make things work as per your proposal. Build some kernel (don't care about memory loss), boot and find what his firmware prefers to do with address space (or else read up the BIOS documentation!) and _then_ again build a new kernel, this time selecting the options appropriately ... Also, note that the change you're proposing is unnecessary! As Andi pointed out, this issue has more to do with broken BIOSen and the proper fix for Tom is to contact his vendor and flash / upgrade the BIOS firmware. I don't see anything wrong with the Kconfig help texts. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
