Re: Feature request: support booting from memory mapped ISO

Visopsys already supports RAM disks, but not as boot disks (yet). I haven't checked out those links of yours yet, but do they describe a method for setting up a RAM disk pre-kernel, and a way for the kernel to search for, and identify that? Yes. See the INT13h subsecton on the MEMDISK page for more...

Would it be possible to support a ramdisk based filesystem? MEMDISK of Syslinux can boot ISOs and floppy images (and provides INT13h access to this memory mapp...

New GPT partition type GUID for Linux data partition

There is a new GPT partition type GUID for the Linux data partition, so Linux and Windows data partition can be differentiated. Previously Linux used the same GUID for the data partitions as Windows. Linux never had a separate unique partition type GUID defined for its data partitions. This created ...
