Boot partition beginning past 1024 cylinders
Trying to make 3 or 4 bootable partitions on one disk is getting a little
tight. Where do we stand with the limit on the first cylinder of bootable partitons? Have the BIOS standards people dealt with this yet, or do boot managers work around the problem ok? -- Reply in group, but if emailing add 1 more underscore and remove the last word. |

So it depends on the MBR bootcode. Newer OSes use Int13ext instead of Int13. |

I use Grub, which boots both Linux and Windows XP without problems. Arno |

Tom Del Rosso va escriu Trying to make 3 or 4 bootable partitions on one disk is getting a little tight. Where do we stand with the limit on the first cylinder of bootable partitons? Nowadays, the only relevant limit is that you need to keep your booting disk below 2TB (MBR architecture). The last mainstream OS release with a 1024-cylinder limit was Windows NT4 (end of extended support this month.) BTW, the first cylinder only matters with respect to the MBR code; after it, the boot loader may also have issues, and it would be the last cylinder of the partition which would matter (in fact, the highest cylinder of the files used, which could be significantly lower, but it is a bad idea to play with that.) Have the BIOS standards people dealt with this yet, Yes, around 1992. or do boot managers work around the problem ok? They do quite well, for quite some time now. Antoine |

"Tom Del Rosso" wrote in message ... Trying to make 3 or 4 bootable partitions on one disk is getting a little tight. What does "getting a little tight" mean? Partition limits of 4 primaries or 3 primaries + 1 extended are imposed by MS HD architecture, that hasn't changed. But you can use BootIt NG unlimited partitions to get around that limitation (w/ caveats). Where do we stand with the limit on the first cylinder of bootable partitons? What limit? First sector is the boot sector, you referring to that? A good boot manager can be loaded from first sector, from which most any OS can be booted from your other primaries. Have the BIOS standards people dealt with this yet, or do boot managers work around the problem ok? Not a BIOS issue, HD architecture issue specific to Microsoft.
