Just for the record, I think the problem is that DEVLOAD only looks for block devices and will overwrite existing CDS entries if there is no associated block device. Which is the wrong thing to do. Regards, Christian --

I hope there's a remedy to this, if this is the case. Yes; patch DEVLOAD (or get someone to do it). I'd have to find other .SYS block device drivers to see how they behave under DEVLOAD, and other device driver loaders like Creative's CTLOAD and whichever program it was that QEMM had.

Hi! There was a question about the which of the algorithms (LZMA, NRV, UCL) is safe for GPL software. A quick review of the UPX web site did not give me a clear answer on which one was used when I specified -9 --8086 for options. Does anybody know off the top of their heads? I
