[N8VEM: 18430] SBC-188 questions regarding Dual SD & BIOS043

Discussion:

Hi everyone,

I have my SBC-188 up and running and I've noticed the Bios (043) appears to
support
the Dual SD card board, which is great. A couple of questions if anyone
knows...

1) Does it use the same port addressing as the SBCV2 using RomWBW? (if not,
what does it expect?)

2) Is it possible to boot into DOS using the SD card, assuming a properly
prepared system on the card?

Also, the BIOS043.zip file up on the wiki appears to be corrupted, I can't
unzip it (tried with 2 different operating systems).
If someone could re-upload it, that would be great. BIOS042.zip
decompresses just fine.

Thanks,

Ed

As I recall, the SD drivers are present in the source, but a lack of
BIOS Data Area space stopped the integration of the driver into the
BIOS.<br>
The init and read/write calls are operational, but will have to
specifically be loaded with any code at this time.<br>

It would need to be the first hard disk driver, making it the C:
drive.<br>

My download of BIOS043.ZIP compares exactly with the original here. 
Both copies check with 2 different un-Zippers, one on MSDOS, the
other on Linux.  I'll send the original by direct e-mail.<br>

I downloaded the 043 BIOS from the wiki and used it to program my SBC-188
BIOS two weeks ago and had no issues.
