[parisc-linux] How to Boot CD on C110

[Daniel Williams]

OK, so SEArch should see the CD drive regardless.  Should it also see 
the FWSCSI internal HDs?  They don't have anything on them...  But the 
Firmware doesn't show anything after its done searching, not the 2 HDs, 
the CD, or the DDS tape drive.  Whats that about CD option jumpers set 
wrong?  What should the correct configuration be?  The pins that it has 
on the back (its a HP branded toshiba XM-5401B 50pin narrow) are ID1, 
ID2, ID4, PRTY, PRV/ALW, TEST, and TERM.  ID2 and PRTY have jumpers 
connected, the rest are not shorted.  The CD drive case is an HP 
external drive with 2 HD50 pin connectors on the back.  Comes in 
matching case color and design to the C110.  I've got the cable from the 
external drive connected to the SESCSI port on the back of the C110, but 
the external bus is NOT terminated.  However, when connected to the 
internal 50pin narrow bus, it IS terminated, and bootup does not occur 
nor does SEA see it.  Perhaps the CD drive is whacked, I'll have to do 
network boot then :)  Anyone done that with MacOS X?  j/k.

For making a boot CD, what exactly has to be done to make it boot?  How 
does the firmware recognize that a particular media is bootable and what 
steps does it then take to load the bootstrap code into memory and from 
where on the media does that bootstrap code come?  Can the kernel be 
loaded from a plain ISO or does there need to be special 'first block 
magic code' that will do the rest?

If I try to boot of 'core.SCSI.2.0' it comes back and says ENTRY_INIT, 
nextline STATUS=-7, and then a couple of rows of 8 digit numbers, the 
first being 00000080.  What's it trying to do here?

Thanks again,
Dan
