Summary:

    Unable to boot from installation floppies on Sony PCG-SRX7E/P, 
    Asus (CUV4X?) MB, Intel SE440BX2 MB, due to missing acpi.ko or
    inability of loader/kernel supplied with installation floppies to
    run without it.



Otterr suggested that there may be ACPI issues with the ASUS MB (see
snippet at bottom of this message).

Just for a sanity check, I have tried booting an Intel SE440BX2 MB system
with the 5.0-20020314-CURRENT floppies, and obtain the same general results. 


When mfsroot has loaded,

acpi_load=YES
hint.acpi.0.oem=PTLTD
hint.acpi.0.revision=1
hint.acpi.0.rsdt=0x03ffdd71

and this runs through the 'ACPI autoload failed - no such file or
directory' message, assumed from the code snippet of i386_module.c
shown in the next portion of this message.  It is then followed by
(taken from a run where the boot process was un-interrupted by any
keyboard interaction other than <ENTER> once mfsroot floppy had been
inserted):

Please insert MFS root floppy and press enter:

-
Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [/kernel]...
ACPI autoload failed - no such file or directory

       00 00 00 00 00 00 00 00-00 00 00 00 00 00 00 00
BTX halted



If I 'OK unset acpi_load' (code for these functions appears to be
src/sys/boot/i386/libi386/ i386_module.c v1.5 and biosacpi.c v1.1)
then i386_module.c should *not* try to load acpi:

    /* autoload ACPI support */
    /* XXX should be in 4th keyed off acpi_load */
    if ((getenv("acpi_load") && !getenv("hint.acpi.0.disable"))) {
        error = mod_load("acpi", NULL, 0, NULL);
        if (error != 0)
            printf("ACPI autoload failed - %s\n", strerror(error));
    }

However, from the 5.0-20020314-CURRENT floppies, this results in 
(the same as above) BTX dump of:

OK boot

just in case something has changed in the way to create floppies...

fdformat /dev/fd0
dd if=kern.flp of=/dev/fd0

(you never know -- that has been about the same since I installed
FreeBSD 2.2 -- some things *do* change)



Anyone else trying to install from floppies onto an ACPI-enabled
machine?  The silence is deafening...
