Hi Wayne,
I briefly checked the new B21 BIOS, but it looks like SD is not working at all. I got
A0>j:
SD: 51 00 00 42 01 FF --> RC=20 TOK=00 [CMD ERR]
BDOS ERR ON J: BAD SECTOR
I tried your compiled BIOS and compiled one myself with different settings, but the behaviour is the same.
I will check thoroughly in the evening. Maybe I did some mistake.
Best regards
Martin

Subject: [N8VEM: 14275] Re: RomWBW V2 Beta
Yet another refresh of the RomWBW v2.0 Beta. It is found in the RomWBW folder and the file is called "RomWBW2-Beta.zip". On startup the banner should reflect v2.0 B21.
It primarily includes various compatibility fixes in the SD Card driver and support for SDHC/XC card types.
Thanks,
Wayne

- Now has two different builds for N8. One for the prototype called n8_2511 and one for the new production board called n8_2312. The 2312 variant has the proper configuration for the new SD card circuit courtesy of David Giles
- Increased the initialization timeout in the SD card driver. I'm hoping that helps with the recently reported timeout issue.
- The ParPortProp variant (zeta_ppp) now defaults to the VGA display and PS/2 keyboard for all console interaction.
I will leave it to Douglas to describe any/all changes to his applications.
I intend to do a final release of v2.0 next weekend. If anyone finds any significant issues, please let me know!
Thanks!
Wayne

Although the code has been stable for some time, I would not recommend folks use this in any system that you want to be super stable. I am making a beta version available to expand the testing and get feedback.
From a general use point of view, things look pretty much the same as v1. However, thanks to more memory being available, there are now typically 4 mass storage drives (slices) available.
Douglas Goodall has overhauled his support app suite (now in Aztec C). David Giles' in-situ flash programmer is included along with his CSIO SD driver support for N8 (requires a custom build). A preliminary version of the ParPortProp build is also included.
This release introduces an "HBIOS" layer that handles all hardware interaction (thanks to John Coffman for steering me in this direction). CBIOS is now just a layer that uses the HBIOS. The HBIOS functions are documented in the doc directory, but are likely to change over the next few months. Thanks to the banked memory implementation, there is now about 25K available for driver expansion without impacting the OS footprint at all.
I look forward to any feedback!
Wayne
