Which version? Dynamic x86 support for x86_64 was added in 2019 (svn r4260).

So it is basically exactly like MS-DOS Player, but more accessible to us Westerners. I am looking forward to trying it!

Which is VERY close to his suggested 519 cyl. He might have backed off on the cyl count for other reasons. Yes. I configured this many years ago, and I remember that I wanted to use the same image for DOSBox svn (at the time), DOSBox-X and DOSBox-staging, one of which had problems with 520, so I …

Re: Open Watcom C++ 16 bit: issues with allocating huge memory and catching bad_alloc exceptions
Posted on 2025-04-04, 16:35
You should be able to allocate more. Try an array of 30000 longs! That should be larger than 64KB. Not even this: operator new exists only with a size argument of type size_t , and this is 16 bits long. This seems to indicate that for dynamic huge memory allocation, you would have to use different …

Re: Open Watcom C++ 16 bit: issues with allocating huge memory and catching bad_alloc exceptions

I guess because size_t is 16 bit, you cannot even create an array with more than 64k entries. Your value gets truncated to the least significant 16 bits. Also, in h/new, it says: NOTE: Open Watcom currently does not throw std::bad_alloc on allocation failures.

Re: Which CPU is the Fastest in the World for Real Mode Operations in MS-DOS?
Posted on 2024-12-16, 18:22
It would be interesting to know if there are modern CPUs that exhibit different behavior in "real" real mode (i.e. bare metal DOS, no virtualization) vs. virtualized real mode (DOS under VMWare, KVM, …)

Are you actually running the benchmarks on DOS? Yes, I ran it on real DOS. I also suspect, and practically confirmed based on the TDP experiment, that under DOS the CPU is stuck in the lowest operating frequency. In recent generations there is a increasingly huge difference between the lower/ …
