Have you tried using a different floppy - they go bad sometimes.
I have try with many floppies. and also with the bootnet.img. Note when the error arrived, the shiftlock and numlock leds are blinking.
How much RAM is in the computer?
The symptoms are similar those of bug #64530. Does reduing the mem= boot parameters (for example mem=240M instead of mem=256M) or disabling power management in BIOS change the behaviour?
The system report 262144KB I have try with mem=240M but it s the same With this (as see in the #bug64530 ) mem=exactmap mem=640K@0 mem=119M@1M I have succefully start the installation (but why ?)
The probing of the memory on this machine isn't correct, so you have to pass the correct map.
