Tested floppy boot on two machines (one PII 350, one 486DX4) Floppy boot with syslinux is very very slow, more than 18 mn to boot a linux kernel from floppy on the 2 machines. Tested with 3 different disquettes that were know to work, boot is reached after this very long time. Noise from floppy head make think floppy wait approximatly one minute between each read. No problem with pxe boot with Intel boot agent v4.19 and e100 and 3.36-pre8 Going back to syslinux-3.20 or 3.35 make the two machines boot normally with syslinux and floppy. Gilles

If you don't want to test them all, do a binary search. -hpa

Pushing 3.36-pre10, *with* the fix this time... -hpa

I will make this version available to the person who had the regression from syslinux-2.11 to 3.11 and 3.20. Thank Gilles
