Hello Alan,
As previously discussed, I've slighlty arranged the version identification
code in the 2.2.18 megaraid driver so that it correcly sees bios and firmware
versions on a netraid. Without the patch, I only get smileys and hieroglyphs
because the version is interpreted as a string which it is not, on the netraid.
On the netraid I have here, the fourth byte in the version is always 0x20, which
I used to identify the version coding because on a megaraid, I have a number
here instead. I'd like people who also have a netraid to test if this is enough
to catch their bios and firmware releases too.
Here comes the small patch. Please note that I extended the version length to
8 bytes to conform to the syntax the bios uses : letter.2digits.2digits
The old undefined code under #ifdef HP has been removed since it was buggy
anyway (char >> 8 always gives 0 ...)
Regards,
Willy
