And DOS so far requires the closed-source "eltorito.sys" driver from
http://www.nu2.nu/eltorito/
An atapi-driver named UIDE (with sourcecode) exists as well at
http://johnson.tmfc.net/dos/driver.html , but author has no experience
with eltorito booting whatsoever, which prevents adding this feature.
Any idea if the ReactOS CD or a (QEMU? Bochs?) emulated harddisk would
work with Memdisk-ISO?
I've so far used the memdisk-iso from the boot-land forums, no idea if
any precompiled new test version is available (including the
syslinux.com DOS installer fix from last week or so).
To go offtopic: can the Syslinux binaries be compressed? UPX
(upx.sf.net, executable files compressor) chokes on it at least.
