Re: [epia] Unknown bootloader class

[Mark Wilkinson]

Hello HyungJong

Thanks for the config information. I can only see one difference between your 
config and my own. That is the CFLAGS32+= -DASK_BOOT=3 
-DANS_DEFAULT=ANS_NETWORK line, which I don't have enabled, but I can't see 
that being the cause of your problem.

Just for Information, I'm using version 1.16 of mkelfImage

As for you second question, I'm not sure about the values in raminit being 
optimised. I think they are configured to 'work' for 64Mbytes of memory - any 
more just get's ignored. For my 128Mb system, I've changed to the following
                  5a = 0x08
    5b->5f,56,57 = 0x10
as these are what the original BIOS set for my memory module.

Andrew Ip may be able to tell you more on this. 
The one document I've not seen is the BIOS porting guide. Just can't seem to 
find it freely available on the web.

[epia] Unknown bootloader class

Hi HyungJong,
    I've finally managed to get to the point where I can give the configs a try 
(one with -DTAGGED_IMAGE enabled, one without)

in both cases, the boot sequence reported that the bootloader class was 
unknown (Type = 0x00000000), but the system then went on to boot the loaded 
kernel quite happily (see attached capture file)

I've also attached the romimages as well
file :- 
lb+eb-elf = linuxbios + etherboot (elf images only)
lb+eb-tag+elf = linuxbios + etherboot (tagged and elf images)

if you still don't get any further, I think it time to look at the kernel 
configuration once again.... the command line you specified did have the 
correct disk partition listed as root didn't it ? I seem to recall that you'd 
configured /dev/hda3 as the root partition, does this match with where / 
really is ?

I could'nt get any more than 64mb of ram recognised using the raminit.inc
approach, and even that 64mb was showing lots of errors.
So i reworked things to uses the generic spd stuff.
I did intend on producing a patch to send in to Andrew IP, but i ran out of
time then my linuxbios got out of sync with the CVS etc. I'll try again soon
but i am very busy at the moment.

I think I have a fix.  I'll check it in once I have double check the fix.  It
is just a stupid mistake.
