Syslinux - Jan 2005 - memdisk fails to boot HD image, if the system does not have an HD

memdisk fails to boot HD image, if the system does not have an HD.

Has any seen this?  Is there a solution?

memdisk output:

Disk is hard disk, 9216 K, C/H/S = 9/64/32
Total size needed = 2063 bytes, allocating 3K
Old dos memory at 0x9dc00 (map says 0x9dc00), loading at 0x9d000
INT 13 08: Failure, assuming this is the only driveold: int13 = f000799a
int15 = f000f859
new: int13 = 9d000008  int15 = 9d000286
Loading boot sector... booting...

Non-System disk or disk error
Replace and press any key when ready

I saw quite a bit of this on IBM HS20-8843 (required hardware
reprogramming) fixed in rev05 hardware and HS40 systems I needed to
leave the pxe images uncompressed all the time.

Hmmm... DOS is hideously dependent on poking magic values in various 
BIOS locations.  Unfortunately I don't think I'll have time to rip apart
a system to run without HD any time soon, although I might be able to 
turn the HD controller off in the BIOS.

Unfortunately, it's likely to still be BIOS-dependent, and you didn't 
give any BIOS details.
