Sorry for your Award BIOS, maybe it's too old, you've to consider change a motherboard. >FreeDOS has no such drivers, so as soon as it hits the >first partition beyond the first 128 GB, it shows an error >message and stops looking for drive letters. Otherwise it >works fine and accesses all drive letters in the first >128 GB okay :-). You sure it's the problem of FreeDOS? I think we need Bart or Jeremy to clear up this. Isn't FAT32 suppose to handle 32bit address (2 TeraByte)? You must be skipped my test of the IBM eServer RAID 5 with three 76GB hard disk, it already surpassed 128GB (148GB) but FreeDOS still works! >If FreeDOS could re-scan the partition table after loading >the UDMA2 DOS driver with built-in LBA48, FreeDOS could even >reach beyond my BIOS limit... Several months ago I've formatted a 160GB hard disk with FreeDOS and it can boot normally, I'm using the 2035a-unstable Kernel and Arkady's FreeCOM. As I know it's NOT related to UDMA2, Jack explain this many times but you must be skipping his messages and not studying his UDMA2.ASM source code. Try not loading it and compare the result. >But to answer your question: If the BIOS thinks that your disk >is only 128 GB, it supports no LBA48. Usually a BIOS can see 120GB hard disk can handle 160GB too, if this kind of weird BIOS exist, we have to put it on the homepage and let everyone avoid it.
