Re: [Freedos-devel] writing a loadable block driver for 4k-sector drive (Questions)

Hi! To put it in un-technical terms, I am talking about a block device driver which tells the kernel "hey here is a nice FAT partition, 512 bytes per sector" but when a DOS kernel asks the driver to read or write sectors in that partition, the driver will actually access a 4096 byte per sector di
