Well its kind of pre-ananconda but Im not sure where to file it. On my Palmax
PD1100 the disk is not bootable. It does boot (same disk) on other systems.

What type of device is this (pcmcia, usb, etc)?
Comment 2 Alan Cox 2002-06-06 12:09:13 EDT
Bog standard IDE CD-ROM. Only known restriction it has is 'no DMA' but the BIOS
knows about that and our boot kernel hasnt kicked off at this point.

Comment 3 Michael Fulbright 2002-06-06 12:38:46 EDT
The only factors I know of influencing the booting via the el Torrito mechanism are:

1) BIOS support. We use the 2.88M image option which some BIOSes choose not
   to implement.

2) Your CD media isn't happy with the CD drive.

Seriously I can't think of any other reason this wouldn't work.  You can easily
test this with a 1.44M image by using this command line:

mkisofs -b bootnet.img -c bootcat bootcd/ | cdrecord -d                        
                                                           ev 1,0,0 -v -eject
-blank=fast -

where you've put the bootnet.img into a subdir called 'bootcd'. I do this all
the time instead of making boot floppies :0

Also, you can try the test ISO at


This uses ISOLINUX instead.

Closing due to inactivity - please reopen if you have additional information to add.
Comment 6 Alan Cox 2002-08-22 12:34:33 EDT
Isolinux works on the palmax

(It took a while to find out because the PSU blew up in the mean time)
