| Summary | 09107: pcipc(s7): Bios cannot recognize the hard disk size correctly. | ||||
| Description | As a result, we have a stuck at the middle of formatting before OS install. | ||||
| Steps To Reproduce | Select an attached blank CHD as a hard disk image (its actual logical size is 5120 MB) and go to BIOS settings menu. | ||||
| Additional Information | sis85c496 machine from pcipc_sis driver also has this bug (see the screenshots). | ||||

A lot of older bioses had limits on what size hard drive they could properly support. For example, a 386 computer would not normally handle more than 512MB. DOS itself is limited to 2GB maximum. Using a 5.4 GB drive? No idea what support you could expect. |

As I noted earlier, the real HD size is 5.0 GB. For some reason, BIOS "sees" a 249 MB more than HD really have. |

What C/H/S parameters did you use to create the disk? The numbers it’s showing are correct for the suggested C/H/S mappings: * 512×652×255*63 = 5,362,882,560 bytes, rounded to 5,363 million bytes * 512×16,384×16×40 = 5,368,709,120 bytes, rounded to 5,369 million bytes * 512×8,192×32×40 = 5,368,709,120 bytes, rounded to 5,369 million bytes 5 GiB = 5×1024×1024*1024 = 5,368,702,120 bytes. It’s seeing the correct size, and giving three suggested mappings that give no more than the actual size. You’re confusing the displayed value in megabytes (MB, 10^6) for mebibytes (MiB, 2^20). If you can’t give actual evidence that it isn’t detecting the disk correctly, this should be closed. |

The premise of the report, that the BIOS is choosing an incorrect size when detecting the disk and choosing geometry, is incorrect and based on a bad assumption. |
