Released version 2.90.05, which changes the way the virtual CHS geometry is determined when working in LBA mode. Additionaly, a custom disk geometry may be given as a command line argument in case the one detected by Ranish is wrong.

The standard geometry table (given in README.md) Ranish uses is now only used if geometry information returned by BIOS is obviously wrong. It is obviously wrong if head count is <= 16 while the disk is greater than >504 MB.

In the previous release the head count was unconditionally set to 255 heads if disk is larger than 4GB. Having thought about it for some time it seems not such a great idea, because some BIOSes for example return 256 as a head count. If in such a case 255 heads and 63 sectors per track must be used it may be forced with part.exe -g 0,255,63. Total cylinder count then is calculated based on disk size and given heads, sectors per track.

A also think the releases are a little bit hard to find. In that area Gitea could use a little bit of rework.
