The problem with operation of IMA of images of HDD is more than 2GB - Beavius - 2015-04-22 06:54
Im create HDD image from physical hdd 3,5 GB.
On this hdd one boot partition 3.5GB, FAT32 and installing DOS(from win98).
On this partition there is a lot of different files, the total size of all files is more than 2 GB.
Im Boot from an HTTP target:
samboot http://192.168.0.1/disk.ima
Perfectly booting DOS, everything works, very thanks to the author of ipxe
Files which are located on a disk less than 2GB physical hdd addres(lba) - read perfectly.
But there is one problem:
The file which data are above to boundary of address space of HDD more 2GB, reads not correctly.
I have an assumption that somewhere in the IPXE program - addressing restriction is put (2GB maximum).
Please check the IPXE program and correct an error.
If additional clarification is necessary, I am ready to a discussion.
Thanks.

Most DOS software are not able to address above 2GB because of the 32-bit boundary and some FAT limits (I can't recall the exact details). You most likely need to mount multiple disks to make it work or use iSCSI/AoE instead of HTTP sanboot.
