memdisk not booting .ima unless there is a floppy drive

Hi, bit of a newbie if I'm honest but was wondering if issue mentioned here: http://syslinux.zytor.com/archives/2006-October/007586.html was ever fixed? basically I have the same issue with the same machine.

I have 4 different types of PC's here that i'm trying to boot by USB stick. It works fine on 3 of them, but on the 4th, A HP/Compaq dx2200 MT, memdisk will not boot the .ima unless the machine has a floppy drive in it, it just gets to 'loading boot sector... booting...' then a flashing cursor under it. I've tried disabling the floppy controller, setting the a: drive to 'none', using raw and bigraw, but no luck.

This is with SYSLINUX 3.61

Typically we have more of the HP machines then the other 3 types....

I don't have a specimen of a failing machine, which makes it hard to fix
- I have fixed some machines, but not others.

A detailed description of the messages printed *might* give a clue why
it's failing on your particular machine.

This is what it displays (its identical wether the machine has a floppy or not):

And if theres a floppy drive it then says starting PC Dos and boots, otherwise it just
hangs there with a flashing cursor.

Can you try a newer version, 3.61 is the latest, and may include fixes
which will solve your problem. Remember to match memdisk and
isolinux/syslinux/pxelinux/etc.

I thought you mentioned before you were using 3.61, but the output above
shows memdisk 3.52, if you are running two different versions, that
could contribute to your problem.

Oops, I had both versions and must have mixed something up, now using 3.61 but still the same issue (same output as before)
