All PentaWare products work properly and as expected on 32- and 64-bit systems as is required by Microsoft Certification Rules. Regardless of whether the platform is 32-bit or 64-bit, ZIP is offered as 32-bit (compatible with version 2.04g) as well as 64-bit. 64-bit archives produced using PentaZip can be opened using competing products. 64-bit archives produced using competing products such as WinZip and PKZip are properly opened and can be extracted from using PentaZip as well as our Command Line Versions.
IZArc can be used on a computer running Windows 11 or Windows 10. Previous versions of the OS shouldn't be a problem with Windows 8 and Windows 7 having been tested. Windows XP is supported. It comes in both 32-bit and 64-bit downloads.Filed under: IZArc DownloadFree File ArchiversFile Archiving SoftwareWe have tested IZArc 4.5 against malware with several different programs.

ALZip can be used on a computer running Windows 11 or Windows 10. Previous versions of the operating system shouldn't be a problem with Windows 8, Windows 7 and Windows Vista having been tested. Windows XP is supported. It comes in both 32-bit and 64-bit downloads.Other operating systems: The latest ALZip version from 2023 is also available for Mac. For Mac applications, we recommend finding a reputable source to download software online, often in the form of a DMG or PKG file.
MX5 has problems with DMA via the 2 64-bit PCI slots when this DMA crosses a pageboundary. The 32 bit slots don't have this problem because the PCI-PCI bridge chip doesnot allow the offending transfers. The SRM code knows about the problem and refuses tostart the system if there is a PCI card in one of the 64bit slots that it does not knowabout. Cards that are ``known good'' to the SRM are allowed to be used in the 64bitslots.
Installing a 2Mb cache module achieves, apart from a 10-15% speed increase (based onbuildworld elapsed time), a decrease for PCI DMA read bandwidth from 64bit PCI cards. Abenchmark on a 64-bit Myrinet card resulted in a decrease from 149 Mbytes/sec to 115Mbytes/sec. Something to keep in mind when doing really high speed things with 64 bit PCIadapters.
Rawhides are available with a 8 64-bit PCI / 3 EISA slot expansion backplanes (called``Saddle'' modules). There are 2 separate PCI buses, PCI0 and PCI1. PCI0 has 1 dedicatedPCI slot and (shared) 3 PCI/EISA slots. PCI0 also has a PCI/EISA bridge that drivesthings like the serial and parallel ports, keyboard/mouse etc. PCI1 has 4 PCI slots and aSymbios 810 SCSI chip. VGA console cards must be installed in a slot connected toPCI0.
Tincup has 5 64-bit PCI slots, one 1 32-bit PCI slot and one EISA slot (which isphysically shared with one of the 64-bit PCI slots). There are 2 separate PCI buses, PCI0and PCI1. PCI0 has the 32-bit PCI slot and the 2 top-most 64-bit PCI slots. PCI0 also hasan Intel 82375EB PCI/EISA bridge that drives things like the serial and parallel ports,keyboard/mouse etc. PCI1 has 4 64-bit PCI slots and a Symbios 810 SCSI chip. VGA consolecards must be installed in a slot connected to PCI0.
