[LinuxBIOS] CONFIG_ROM_STREAM verus CONFIG_IDE_STREAM verus CONFIG_FS_STREAM?

[Steve Isaacs]

I'm puzzled about the difference between these options. If I want to
boot using an IDE device does the following make sense?

## Boot linux from IDE
default CONFIG_IDE=1
default CONFIG_FS_STREAM=1
default CONFIG_FS_EXT2=1
default CONFIG_FS_ISO9660=1
default CONFIG_FS_FAT=1
default AUTOBOOT_CMDLINE="hda1:/vmlinuz"

I found these in mainboard/momentum/apache and am wondering if I can use
them as is for my board.

Am I correct in interpreting this as: Use the IDE interface to boot
which can contain an EXT2 or ISO9660 (CDROM) or FAT file system? (This
is what I want -- simply boot Linux using the ATA drive connected to the
IDE interface). I'm currently able to boot this way using a proprietary
BIOS and want to do the same using LinuxBIOS.

How does CONFIG_IDE_STREAM effect this? Does it control which IDE
interface to use with a default of 0? e.g. I have an ATA drive as the
master and a CDROM drive as the slave on the IDE interface. If I change
CONFIG_IDE_STREAM to be 1 will the boot be from the CDROM drive?

I'm not sure how the AUTOBOOT_CMDLINE needs to change if the boot device
changes.

If CONFIG_ROM_STREAM is equal to 1 does it compliment or override or is
it overridden by CONFIG_IDE_STREAM? Or, are they two entirely different
things?

Do I need a specific payload before any of these will take effect?

Thanks,

Steve

Don't use those, they're for an old FILO 0.42 payload. Get the latest
version of FILO (directions in the wiki), and use that. The readme and
config file explain pretty much everything.

Where is this from? There's no such board in LinuxBIOS, AFAICS.

You want to use the latest FILO version from svn, see
http://linuxbios.org/Filo

Which board and chipset is this btw?

I didn't realize I was looking at a directory that has since been
deprecated and apparently removed?? Here's the contents of entries from
the .svn directory. No wonder I received the "don't use that" response.

You're asking which board I'm using? This is a board using ht1100 and
ht2100 chipset from Broadcom. Neither of these are currently supported
in the LinuxBIOS source set.
