New or Old Bios w/Onboard IDE?

So I've read all the posts about how all the new and different bios versions behave, but I am still curious why the new bios is necessary. From what I have read, it has something to do with the PCI/ISA slot function? Correct me if I am wrong.

So what features is the original bios missing that makes the change necessary? It is possible to boot the onboard IDE with the original bios, no? Nothing I have been able to find gives specific details about configuration to boot from the onboard IDE. My questions are:

- Original Bios, yes or no?
- Drive jumpered as master or slave?
- Bios boot order, C Only, C-CDROM, D-CDROM?
- Disk On Chip, pull or no?
- Autodetect drive params or enter manually?

Thanks in advance...

Yeah, I know what you mean. I have been curious about this also. Most people that post good info are using ISA - IDE. I have done the IDE rework on the WS but have been unable to get it to recognize a HD. I have tried all the bios/HD Jumper setting combinations I can think of, DOC in and out, Still doesn't boot or even recognize the HD. Anybody care to elaborate? Or point us to a thread with the answers?
THX!

I have the onboard IDE working great, but it was like pulling teeth to get it that way.
Orginal bios, DOC pulled,and I just jumperd the MB with wire and solder. After days of frustration I finaly broke down and got a cheap continuity tester and tested every circut on the IDE header(did find some problems). The rest of the problems were all in the bios. I cant tell you the exact settings but if I recall, the boot order
(C only is what I have), and udma enable/disable are important settings. The bios was able to auto detect the drive.
I cant say enough about getting a continuity tester ($15). If continuity checks out ok,it will work with the bios tweeks. It has become one of my most used tools!!!!!
Good luck!

Everything works for me w/original Bios except USB. (Now - on board IDE. Originally tested w/ ISA IDE – no problem as well).

Tanker: when you say 'jumpered the motherboard with wire' were you talking about the resistor pack pads? I blob soldered over the resistor packs to get me going until the correct parts arrive from Digi-Key. Did either of you do it that way? I'll have to get my meter out. Now that I think about it, it is quite possible that some of the pins might be flux insulated. I'll check that.

Yes I am talking about the resistor packs.
But you cant just fill the whole pack up with solder. Each pack should have 4
(or is it 5???)differant wire jumpers.
OOOO
llll
