[syslinux] isolinux: Extremely broken BIOS detected

Try if Memtest86+ (www.memtest.org) ISO (burned to cdrom) works.
It also uses non-emulation, and is just 100KB or so to download:
http://www.memtest.org/download/1.40/memtest86+-1.40.iso.zip

H. Peter Anvin also has a small ISO at:
http://www.kernel.org/pub/linux/utils/boot/syslinux/Testing/vesatest/isoimage.gz

but I have no idea how he got his ISO image so small!.
MKISOFS seems to add a few 100KB (I tried recreating the Memtest86 ISO by using isolinux instead, then chainloading to memtest)

Only thing that now seems possible is to recreate your own cdrom:
create a 2.88MB floppyimage and put Linux kernel and initrd in it (maybe use SYSLINUX for it?), then remaster the cdrom using floppy emulation (with 2.88MB bootimage).
Most modern Linux distro's use Isolinux, not a thing you can do about it.
As there's so much bad BIOS existing in the world, indeed there are a lot of complaints.

If you're able to use Linuxbios as system bios replacement, and then get Isolinux to work (not possible yet, IIRC), be my guest :)

I think your IDE drive will work! Most modern BIOSs are pretty decent.
(otherwise they would not succeed in adding booting from USB!)
My Yamaha SCSI CDRW also failed, on LSI1010-66 SCSI controller.
