This has come up enough for me to change the bootblocks a bit..

here is the change I suggest:

> from:

> loadstart:
> 	/***************************************************************\
> 	* As a default set it to the first partition of the first	*
> 	* floppy or hard drive						*
> 	\***************************************************************/
> 	part = unit = 0;
> 
> to:
loadstart:
        /***************************************************************\
        * As a default set it to the first partition of the boot        *
        * floppy or hard drive                                          *
        \***************************************************************/
        part = 0;
        unit = drive & 0x7f;
#ifdef  BOOT_HD
        maj = (drive&0x80 ? 0 : 1);             /* a good first bet */
#else   
        maj = (drive&0x80 ? 0 : 2);             /* a good first bet */
#endif  

I'm checking in this change now.....

define BOOT_HD to make it default to hd(1,a)/kernel

If that fails in the older boot code:
replace 
part = unit = 0;
with
part = 0;
unit = 1;
maj = 1;
