Re: [Freedos-user] XMM on AMD Opteron 6274

FWIW, I've had computers where MS HIMEM.SYS + EMM386.EXE worked and one or more of the FreeDOS ones (JEMM, HIMEMX) crashed, and vice versa. On the majority of systems I think they all work OK, but it really depends on the hardware. ---

- rugxulo@Hello. I use PXELINUX 4.05 20130513. It works fine with MS-DOS (Win98) with MS HIMEM, but fails with FreeDOS / any XMM. That is why I don't point to PXE loader's problem.I can give it a try with latest pxelinux or try iPXE to be burned into ROM. 14.01.2014, 03:15, "Rugxulo" :Hi,On Mon, Ja

Hello. I've faced a problem with running any (XMGR, JEMMEX, HIMEMX) XMM on AMD Opteron 6274 (have tried Supermicro H8DGU and Asus KGPME-D16).  -- XMGR just hangs a system (xmgr-hangs.png).  -- HIMEMX lead to reboot the system if I've specify DOS=high[,umb] otherwise I've got unusable DOS/32A apps s
