Likely he was confused bout the "real" 2.8 floppy and the 1.8 Mb an XDF-ed 1.4
floppy can take.
An XDF-ed 1.4 floppy still is an 1.4 floppy, albeit it can take 1.8 Mb
read-only.
BTW: An XDF-ed 2.8 floppy would take 3.6 Mb read only of course. But here we
are discussing the angel's gender.



ET> Or, if your BIOS has support to boot from cdrom, put the eCs boot
ET> cdrom in a IDE/ATA cdrom drive (attached to your system and turned on)
ET> and make sure the "Boot from" option in the BIOS is set to cdrom. If
ET> eCs has the system rebooted to start from its boot partition for the
ET> first time, set the "Boot from" option in the BIOS to whatever that
ET> allows that boot partition to be started.

No, no, it wasn't about that I was talking. The eCS GA will have quite a
different system to boot from CD as the actual beta packets do have.

On the GA cd boot, the whole bunch will be piloted into a RamFS virtual disk.
Meaning:

1. In first instance will be created two virtual 2.8 floppies, from which eCS
will do the "three floppy boot". <G>
2. This virtual "three floppy boot" from the two virtual 2.8 disk will end in
an installation on a virtual Ramfs station Z:
3. Out from this virtual station Z: existing partitions will be updated and/or
new partitions created/installed.

This trick wouldn't be possible if OS/2 wouldn't support the 2.8 floppy from
within the kernel, for simply there wouldn't be enough of space for the basic
drivers. And things would have been rather grim for eCS IMHO. That's the reason
why I called the "genuine 2.8 floppy" support a live saver. (As is RamFS in
this respect).

Incidentally, this very week we discovered how to boot from SCSI Adaptecs.
Finally!
